Mypaint crashes on startup in gtkrecentmanager.c:get_icon_fallback

Bug Description

Binary package hint: mypaint

When I open Mypaint the application closes instantly.
This is the messaje from the console:

/usr/share/mypaint/lib/helpers.py:93: DeprecationWarning: PyArray_FromDimsAndDataAndDescr: use PyArray_NewFromDescr.
arr = pixbuf.get_pixels_array()
Setting screen mode for " WALTOP Tablet "

Gtk:ERROR:/build/buildd/gtk+2.0-2.22.0/gtk/gtkrecentmanager.c:1942:get_icon_fallback: assertion failed: (retval != NULL)

I just uninstall the Wizardpen driver but Mypaint continues crashing.

/usr/share/mypaint/lib/helpers.py:93: DeprecationWarning: PyArray_FromDimsAndDataAndDescr: use PyArray_NewFromDescr.
arr = pixbuf.get_pixels_array()

Which version of Ubuntu is this?
Are you using the standard pygtk and GTK versions?
Can you provide a backtrace?

I'm under Kubuntu 10.10 RC.

The same problem when I try to start Inkscape (after changed widget style to Raleigh in GTK+ Appearance in Kubuntu):

> inkscape ~

Gtk:ERROR:/build/buildd/gtk+2.0-2.22.0/gtk/gtkrecentmanager.c:1942:get_icon_fallback: assertion failed: (retval != NULL)

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.
[1] 3244 abort inkscape

I suspected this was not MyPaints fault.

Alvaro, are you also using the Raleigh GTK theme?
Pavel, does the problem go away when you change to another theme?

No, I'm using QtCurve.

I have the same problem now. Actually for the first time program worked fine and then i saved my project in .ora extension and in that moment it crashes all the time. I try with reinstalling but didn't work. I am using MousePen but first time i started program MousePen worked just fine.

Sasa: Does the program crash when you save your image?
If yes, that is a different bug; please file a new bugreport.

@Jon I used one time Mypaint and it crashed when i saves my work. Next time i couldn't start Mypaint at all because it is crashing all the time. So i am not sure if it is because of of my saved work or because Mypaint has general problem with crashing on start up.

If MyPaint has the same output as shown here when run from a terminal, it is the same issue, and you should use the workarounds posted in the duplicatate bug or a bug linked from it. If not, please file a separate bugreport.
If you are able to reproduce your crashing-while-saving issue, please file a separate bugreport.

I am getting the same error like guys before. I am running Kubuntu 10.10.
