Status changed to 'Confirmed' because the bug affects multiple users.

It has not happened in 12.04 it seems. All the duplicates are from 11.10

Omer, I just linked lots of duplicates from 12.04 :)

Just happened on 12.04 Beta 2 playing a youtube video (hmtl5 mode) in full screen

Just happened on 12.04 Beta 2 after inserting usb-flash:)

I'm having to deal with this multiple times a day. So this bug is still very present on a fully updated 12.04 LTS.

That's the most reported issue on errors.ubuntu.com for unity this month with close from 5000 reports, that should be addressed in a SRU if possible for the lts point release

Why is it the latest duplicates of this bug are all Unity 5.10? Is it possible it's fixed in 5.12, or did automatic duplicate detection just start working properly around the time 5.12 was released? :)

@Daniel, not sure but I can reproduce this bug.

Open ccsm using the terminal.
Enable slow animations using ccsm
Minimize the ccsm.
Close the ccsm using CTRL+C while it is minimizing
Disable slow animation
Use unity for a while

@Daniel: likely because Ubuntu turns off apport by default in stable series, which means we basically stop receiving report to launchpad from stable versions (that's one of the issues errors.ubuntu.com aims at solving)

How ironic. The "stable" compiz release doesn't report crashes to Launchpad, because it's the "stable" compiz release. :)

As I've mentioned this is an exceptionally annoying issue, so I've cherrypicked the fix into the current release version of Unity, and did a PPA for it:

https://launchpad.net/~pmjdebruijn/+archive/unity-testing

Previously Unity would crash about 50% of the time whenever I closed Darktable (a photography application), with the fixed Unity version from the above PPA, I opened and closed Darktable about ten times without any crashes yet.

So I guess this is confirmed fixed.

This bug was fixed in the package unity - 6.0.0-0ubuntu1

Please use "In progress" instead of "Fix commited" as the status for bugs that have not yet landed in -proposed.
The SRU script will automatically changed it to "Fix commited" when it lands in -proposed and then "Fix released" when it lands in -updates.

Hello apgnu, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/5.14.0-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
