Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed with the default qt4 gui

Bug Description

vlc will hang when trying to open anything additional - it also appears to crash unity-window-decorator among other things (have crash report on that)
Ex.'s - the playlist, tools > preferences and so forth

Switching the qt4 gui to anything but 'default' (gtk+) in qtconfig-qt4 and it works without incidence (tooltips are empty bit otherwise good).

Will attach xsession.errors, reflects a login, opening vlc, opening xsession.errors, then attempting to open playlist window in vlc.
(using nvidia-current)

Note to Vlc users - I've found clearlooks to be best choice, should be good for other apps as well. Also do as mentioned in comment 13

Note to Anki users - please review comments 20, 22 for current workaround

This happens with many Qt4 and PyQt4 applications.

This is a bug with the Qt4 theme, not with VLC. Please reassign.

This is my best guess, still an issue with vlc 1.1.11

I also have this issue with a PyQt application I have written (A guitar synthesiser). As well as the window becoming really large (and causing compiz/unity to crash) as soon as the application is started, X begins to use 100% of CPU.

Hi,

workaround: install qtconfig-qt4 and change gui style to motif.

The GTK+ style seems to be the trigger of this bug.

Hi,

The workaround also works with calibre (see bug #812258), that is heavily impacted by this bug.

Increasing the importance as it makes unusable several applications and make the system unable to restart cleanly (tested in a VM, I had to recover a previous snapshot).

Just wanted to add. note that unity-2d & gnome-shell, while not quite as affected as unity, also show poor behavior (at least here
attached screen of vlc in playlist view in unity-2d, note that the window extends ad-infinitum to the bottom

It also happens with hplip-gui,

This also occurs with thg , however using the workaround does not fix the issue for thg.

This also affects GoldenCheetah; checking to see if changing theme works...

Well, changing the theme to Motif does something, but in Unity 2D metacity still keeps crashing. This isn't looking promising.

Actually, setting the theme to Clearlooks made the application behave properly, at least under the legacy Gnome 2 install running metacity. Still going to check on Unity proper.

Yep, works fine under Unity. So it's definitely got to do with the Qt theme.

SUPPORT NOTE FOR VLC USERS:
If affected by this, after changing the gui theme in qtconfig-qt4 you must also remove this file to regain 'proper ' use again
~/.config/vlc/vlc-qt-interface.conf

There was a major upgrade of qt4-x11 today to 4:4.7.4-0ubuntu1, the,result -
No better, possibly even worse in unity (3d
If this can't be fixed then it should be included in the release notes with at least a short lost of affected apps as not all qt4 are. (vlc certainly is and is a fairly popular add-on app

ect. ect.

This seems also to affect MusicBrainzPicard on my system. Running via terminal i got the following errors:

-------------

I would also like to mention, that in Unity-3D the whole RAM is used and the system starts to write the swap full until the whole system is unusable, where in Unity-2D the RAM usage raises per 1GB and picard's window is drawn wrong.

Running this picard in unity-2d mostly produces the error above, but surprisingly a few times it works without flaws.

This is also an issue running "calibre". The whole systems becomes unusable and hangs.

I would like to enclose my error.log for calibre. Generated on 64 bits oneriric.

The X failure part is in the middle of the file.

Happens with ReText (https://launchpad.net/retext) also.

Also affects Anki, bug duplicated in https://bugs.launchpad.net/ubuntu/+source/anki/+bug/843341

Tried the workaround suggested by rnsmith2 with no effect on Anki problem.

Holger, try purging all configuration files for anki (I believe located in your home folder in .anki) and then try the fix again. I know some people said that was necessary to fix the problem in VLC. My config problems were already purged (really I had uninstalled and deleted everything remotely related to Anki except for my deck and media files in an attempt to fix this earlier), so that might be a step I'm missing in my fix. If that does work for you would you post the update to the Anki Google group for me as well? And if it doesn't fix the problem, I'll try to think of something else.

The rnsmith2 workaround does work for me (wrt Anki). I selected the
motif theme in qtconfig.

I deleted the .anki folder et voila, it worked. Thanks for the workaround and the additional help!

I tried to reproduce this bug with vlc, calibre and anki but could not. Does it still happen for any of you with libqtgui4 version 4:4.7.4-0ubuntu2? If so, can you try this?
- make a copy of the config files (.anki folder for anki, .config/vlc/vlc-qt-interface.conf)
- delete them
- check if it "fixes" the bug
- if it does, attach the config files to this report

@agateau:
I've written a simple test-case PyQt script (https://launchpadlibrarian.net/79590491/test_v2.py), and it still works for me.

Can there be any relationship/dpendency between this bug and bug 813230?

It still happens with vlc using the current qt4-x11, as noted in comments 14 & 15
Will attach the qt config file for vlc - if needed I'll point out the specific area.

Though deleting the config does not fix the issue, Only changing the gui does. (& then deleting the config does fix vlc.

As note in orig. description that this affects vlc when doing certain things, not particularly just opening vlc -

"vlc will hang when trying to open anything additional - it also appears to crash unity-window-decorator among other things (have crash report on that)
Ex.'s - the playlist, tools > preferences and so forth"
The unity-window-decorator crash was relevant 10 weeks ago, no longer is.

After switching the qt gui, deleting vlc's config this is a good config and vlc works as expected

If I replace this one with the one produced with the gtk+ gui attached previously then vlc will open in a borked state

Following comment #5 and #13 I get the HPLIP GUI tools working again. So bug 813230 seems to be the same as this one.

Another PyQT app affected: qbzr (see bug #851379)

Running "bzr qdiff" under xtrace, we get
... lots of verbosity ...
000:<:0125: 20: Request(12): ConfigureWindow window=0x02400010 values={width=65535 height=65535}
... lots more verbosity ...

This does not appear to be an X server problem; it looks like Qt is asking for an insanely-sized window, and then being surprised when it can't render to its 16.4 GB window.

I am still scratching my head trying to reproduce this bug, or at least spot the difference between my system and yours.

I am running Oneiric 64bit, could it be the difference? Does anyone of you is able to reproduce this bug on a 64bit version of Oneiric (note: I mean a 64 bit OS, not a 64 processor) or are you all running Oneiric 32bit?

I'm running 64bit oneiric, and 'picard' is the app that is causing problems here.

I'm also running 64bit oneiric, and qbzr is a 64bit app causing problems.

(Well, bzr is a python program so not in itself 64bits, but the python interpreter and the dependencies libraries should be using the 64bits packages.)

I have this bug and seems can reproduce it. May I help somehow to solve it?

While the orig. bug was filed on a 32 bit desktop & am currently using a 32 bit install on a laptop just booted to todays daily 64 bit
Installed vlc, tried to open the playlist & easily seen.
Terminal showed errors as in descript (X Errors), .xsessions shows 1000's of
"compiz (opengl) - Info: Couldn't bind redirected window 0x3800006 to texture"
use of the session degraded as in screenshot attached

Also did again produce a unity-window-decorator crash - can be seen here if needed
Bug 853897

This has been occurring on various machines since late June, dozens of fresh installs on a weekly basis
The only thing these machines have in common is nvidia display adapters

Since I have that problem on a Intel mobility card, I'd rule out the video driver (or it's a common issue to nvidia / i915, which makes it less likely.)

I have this problem on both a 32bit laptop with an ATI radeon card, and a 64bit with an intel mobility card.

That's not right. Other threads in VLC do call getenv() too, for instance through libdbus or XCB, not just the Qt UI thread.

Update of overlay_scrollbar gtk patch which exposes a function to disable overlay scrollbars.

Updated Qt patch which takes advantage of the function introduced in 100_overlay_scrollbar_loading.patch to disable overlay scrollbars.

Just realized I misunderstood what you said. Indeed this would not be
threadsafe.

The two patches should nail this bug for good. Note that the bug won't be fix until both patches are in, as the GTK patch exposes a function which the Qt patch uses. It should not be a problem if the Qt patch lands first though, as the Qt code checks for the presence of the new function before using it.

The GTK patch makes these changes to the symbols, does anything we know of use them?

As far as I know, the old symbols were only used internally by our
overlay scrollbar GTK patch.

Regarding the new symbols, at least ubuntu_gtk_overlay_scrollbar_new()
could be marked hidden. The new overlay scrollbar patch uses this
function in 3 places within GTK so it can't be made static, but its
visibility could be changed so that it is not exposed to the outside
world. I am going to mark it as G_GNUC_INTERNAL.

ubuntu_gtk_set_use_overlay_scrollbar() must be kept visible, as it is
used by the Qt patch. For consistency I think
ubuntu_gtk_get_use_overlay_scrollbar() should be kept as well.

Aurélien

Here is a slightly modified gtk patch which does not expose the ubuntu_gtk_overlay_scrollbar_new(), as explained in comment #92

As qt4-x11 4.7.4-0ubuntu6 arrived in an update, I logged out and logged in again and then tried to open the Settings window of the hp-systray menu. hp-systray still crashes (so it would still need "LIBOVERLAY_SCROLLBAR=0"). So qt4-x11 alone does not help for hp-systray. Which of the other two is also needed (overlay-scrollbar, gtk+2.0)?

I also still get metacity/vlc crashes with the new Qt. I see:

QWidget::setMinimumSize: (/MainInterface) The largest allowed size is (16777215,16777215)

you need BOTH qt and gtk... but if this still crashes, we could fix
qgtkstyle?

Unfortuantely even with new qt and gtk+2.0 the metacity crash in bug 848808 with overlay-scrollbars still persists.

Also for me: the hp-systray crash is still there.

vlc doesn't work either.

My mistake.

TL;DR: Qt patch was wrong. This new version should work.

Longer explanation:
I first added a function named ubuntu_gtk_disable_overlay_scrollbars() to GTK2, and this is what the current Qt patch uses. Later I decided it was more elegant to instead expose two functions: ubuntu_gtk_set_use_overlay_scrollbars() and ubuntu_gtk_get_use_overlay_scrollbars(). I correctly updated my build of Qt to use these new functions, but forgot to refresh the patch before attaching it.

If you look for me I will be under that large brown paper bag in the corner.

That is really strange. Maybe one of necessary packages is outdated? You
need libqtgui4 >= 4:4.7.4-0ubuntu8 and libgtk2.0-0 >= 2.24.6-0ubuntu4
for the bug to go away.

Aurélien

EricDHH -
in addition to being fully updated you need to delete ~/.config/vlc/vlc-qt-interface.conf or it will keep occuring

Yes that's it, my suggestion is a script that clears out this config by update. Thanks!

Unfortunately we can't do that automatically: packages are not allowed
to modify user configuration files at upgrade.

My guess on what goes wrong is that when vlc was started with versions
of qt and gtk older than the ones I mentioned, it stored a huge window
size before dying. Now that it is started again, it tries to resize the
window to the stored size and dies again.

I don't think the config file can go wrong for stable-only users (ie
users who did not use vlc with qt and gtk from Oneiric alpha or beta) so
that should limit the affected users to people who are more
computer-savvy and can find this bug report. If stable-only users are
affected, we could however patch vlc to limit the size of the restored
window.

hi guys

i have the same problems with vlc (but no with calibre, installed from script) on natty 64 bit

what solution I can adopt to resolve?

from repository:
libqtgui4 is 4:4.4.7.2-0ubuntu6.3
and
libgtk2.0-0 is 2.24.4-0ubuntu2+overlayscrollbar2

I can hope in a backport?

or the sole solution is use qt4-qtconfig?

many thanks

night train

You may want to purge a PPA from which you installed your Gtk (using ppa-purge).

no backports for natty?

if i setup qt4-config to cleanlooks, then i have problems with tooltips unreadable and unmodifiable

if i setup gtk+, then the problems with vlc remaining

please help me

thanks

I don't think there will be a natty backport (at least I am not going to
do it). What you can do is either:

- Uninstall the overlay-scrollbar package
- Switch to a style which is not affected by the bug and does not have
the tooltip issue. I think Plastique should work fine.

This has re-emerged in the current state of 12.10, though in a more limited fashion.
(have nvidia card here

Seen clearly by opening vlc & going either
Media > open disc
or
Tools > Preferences > clicking on 'Show settings > all'
If it doesn't occur the 1st time, then repeat
Removing overlay-scrollbar* & this doesn't occur, or switching qt to another gui like cleanlooks, just like before
(if removing overlay-scrollbar* to test make sure all 3 packages are removed or you'll not be happy

May be best to wait for A1 to re-open or file new?

Just to fill in -
LIBOVERLAY_SCROLLBAR=0 vlc again prevents any bad behavior

So pretty much the same as before, only diff is the affected vlc windows are an impossible width, last time it was height - ex. of Media > Open Disc. (Open Media), window

I would open a new bug and a comment referencing this one. The root cause is probably slightly different now, so reopening would bring confusion.

Bonjour,

Thank you for your reply and suggestion but I have moved from Ubuntu
11.10 to 12.04.
I will see if VLC is more stable in this version.
Regards.
Joe

New bug on 12.10
Bug 1005677

Experiencing this problem developing PyQt5 applications, in regards to QTextEdit items. Currently the only fix is to use a non-native style. See here: http://stackoverflow.com/questions/35351024/pyqt5-gtk-critical-ia-gtk-widget-style-get-assertion-gtk-is-widget-widg

Any ideas of how related these issues are?

Uninstalling overlay-scrollbar package seems to work for me. Thanks.
