Bug Description
I'm running Compiz on NVIDIA 185.18.36, Ubuntu 9.10, Thinkpad T61p, 2.6.31-
If I let the screensaver kick in and the screen get locked, and then go away for a while, *sometimes* compiz.real will crash on unlocking the screen. I haven't yet been able to track down a definite repeatable instance though.
The error in the compiz debug / crash log is:
#0 0xb78ba430 in __kernel_vsyscall ()
#1 0xb7556513 in waitpid () from /lib/tls/
#2 0xb74f8d03 in ?? () from /lib/tls/
#3 0xb7611fad in system () from /lib/tls/
#4 0xb54cd3e1 in ?? () from /usr/lib/

#7 0xb766fd10 in ?? () from /usr/lib/libGL.so.1
#8 0x00000000 in ?? ()
Guess this could be related to X, nvidia driver, compiz, screensaver, rss-glx (I've tried different screensavers), kernel, memory usage... I just don't know :-(

I can also confirm this bug. I have noticed compiz.real crashes with a segfault in libglcore.so while system is under load with the screensaver active. Judging from timestamps within the logs, it appears the crash happens while the screensaver is active rather that upon unlocking it. Again, I only notice this when the system is under load while the screensaver is active.
