compiz crashed with SIGSEGV in std::vector<WrapableHandler<GLWindowInterface, 5u>::Interface, std::allocator<WrapableHandler<GLWindowInterface, 5u>::Interface> >::_M_insert_aux() from GridWindow::GridWindow()

[Sean Fitzpatrick]

Binary package hint: compiz

Crash happened while playing with settings in the CCSM. I had several crashes in both Unity and Classic.
Note: deciding to see what would happen if the desktop cube is enabled in a Unity session is a *very bad* idea!

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue.

This may be very difficult to reproduce, particularly since you very well may not know exactly what you were doing when compiz crashed: Remember, this bug report will deal with one issue, not a broad range of issues. Please try to reproduce the problem that specifically caused this crash on a later version of Ubuntu, such as 11.10 or the current development version (12.04).

Thank you for your help and patience.

[Sean Fitzpatrick (sean-fitzpatrick)]

As I recall, this was a compiz crash while changing settings in ccsm, during beta testing of 11.04 - so the crash report was generated automatically by the system. Right now I'm running 11.10, so apport does not show any crashes when they occur.
However, compiz is overall more stable. It's still possible to cause compiz to restart while playing with the settings, but I have to try a lot harder than before.

Just to see if I could, I enabled the desktop cube. I managed to do this, although it requires temporarily disabling the Unity plugin, which causes a compiz restart. The cube is buggy - windows flicker in and out while changing workspaces - but obviously Unity was never meant to work with the cube. (This test led to the following observation while trying to return to my original settings: it is necessary to disable the 'rotate cube' plugin before disabling the 'desktop cube' plugin. Trying to disable the desktop cube first causes ccsm to segfault.)

So to sum up, there's a segfault with ccsm that probably shouldn't happen, but that's a different bug. I can still make compiz restart by playing with settings, but the system recovers. My guess is that the original bug that generated this report was addressed.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Thank you, Sean, for your quick reply.

Your reasoning is very sound; I feel that the best course of action would be to close this bug - The development is so fast that even the different bug you speak of may have already been addressed.

If you feel that you can accurately reproduce the issue that you reported here, please do re-open it. Otherwise it would probably be best if you open a new bug report. Your help is greatly appreciated :).

[Sean Fitzpatrick (sean-fitzpatrick)]

The segfault in ccsm occurs with the current version in 11.10, but I would not be surprised if it's already fixed in 12.04. I don't have the time at the moment for alpha testing but once 12.04 hits beta I'll upgrade my home computer and see if I can reproduce the bug. (I do some work at home so the first beta is usually the threshold for stability where I'm willing to go live with it.)
If I get some free time I might try installing the current build in a VM, but my desktop at home is several years old and VirtualBox performance is less than ideal.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

Don't feel pressured into installing anything. Remember, you can always test in a livecd environment!

[Sean Fitzpatrick (sean-fitzpatrick)]

Yeah, livecd and VirtualBox are both options, but I find that going that route is fine for testing but doesn't work so well as far as getting my usual work done. So I upgrade once it hits beta, stick to business as usual, and report any bugs that come up as I try to carry out my usual tasks.
