Crash pressing alt+f4 while in shift switcher

Confirming in 8.10, and attaching a screencast showing the bug.
Using compiz 0.7.8-0 and nvidia drivers.
In the video, I hit alt+f4 at about 4 1/2 seconds. The crash handler plugin then loads metacity, and I alt+f2 to get compiz back.

Changed status to confirmed.

I was also able to reproduce the bug on ATI and nvidia cards. I'm attaching a complete backtrace.

Reported upstream so compiz developer can take a look at this bug.

I was unable to reproduce this in Ubuntu Jaunty 9.04. I tried it on a fresh install and with messing around in the ccsm with different configurations and had no luck. I'm running on a ATI x1600 on a Macbook Pro 1,1 with the default Jaunty ATI drivers.

This bug still exist on jaunty, I reproduced it today. It only requires to press alt + f4 exactly at the right moment.

This commit for plugins-main should fix this crash:

http://cgit.compiz-fusion.org/fusion/plugins-main/commit/?id=a02cc081ee17e801b54349365cf077db67674b91

I tested the patch and I confirm that I was not able to reproduce the bug.

This bug was fixed in the package compiz - 1:0.8.3+git20090914-0ubuntu1
