I encountered the same issue when I tried to use Alt+F4 to close a Pidgin conversation window.

 I was changing workspace with Ctrl+Alt+Arrow.

crashes with the same error after I open terminal and press ctrl+q, usually it crashes but not always.

for me, that happened when pressing Alt + F2

is it the same bug https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/737467 ?

Compiz crashed for me again when pressed ctrl+alt+c in terminal while running top command

Alt+F2 for me

Set to critical, getting tons of dup.

I noticed in the dupe bug #741403 that the stack trace starts inside libwnck! From update_client_list() inside libwnck's screen.c line 1771. Apparently wnck emits a "window-closed" inside the Compiz process.

Exactly how wnck has ended up inside compiz is unclear, but it definitely shouldn't be there... Maybe a rogue plugin?

Hmmm... the bug linked in my prev comment seems to be a crash inside unity-window-decorator and not compiz. So maybe wnck is not misplaced there after all...

Fixed by committee

Is there someway to see what code was committed to fix this bug? Linking commits to bug reports might lead to lurking ubuntu users to become ubuntu developers.

HI Jason Smith ,

Thank you.

Should this fix be available in updates through apt-get?

This bug was fixed in the package unity - 3.8.2-0ubuntu1

It's rather invalid, the known crash was in unity

I just encountered compiz crashing in a way that is rather identical to this issue, by pressing <ALT>0<TAB> to switch windows. I have unity (3.8.2-0ubuntu1), so it seems that didn't fully fix the compiz crash.

Well, that bug still happens, for example when pressing Alt+F2. It's neither fixed nor invalid.

bwalex: we have a lot of g_closure_invoke() crashes happening in different part of the code, the other seems to be reported. This one should be fixed though (in unity), the other are still opened for more debugging and crash fix love :)

Thanks Didier Roche for clarifications, I have much less crashes.
But got a few recently. Was worried a bit since it should be fixed.

Lets wait for other reports to be fixed:)

11.04 become more and more stable. Good work.

Switching <ALT>+<TAB> between FF4, Chromium & Document Viewer when crash occurred.

Just to update, we've fixed this bug for the second time (details at https://bugs.launchpad.net/unity/+bug/748033) and you should be getting the goodness tomorrow. I'll dupe this bug with the other one so everyone knows the status in one place, I apologise in advance for the noise this will create :)

Okay, so LP isn't letting me do that, I'll just reassign to myself and re-milestone. If you still encounter this after tomorrow's release (3.8.4) I'd appreciate you re-opening the bug linked above, thanks!

Happened for me again when trying Alt + F2, just after a restart with fresh updates.

ALT + TAB broke compize time after time.

Alex, do you have the latest updates? Testing it with the last compiz package, haven't got any crash yet. Pretty stable for me finally.
