I'm running Compiz on NVIDIA 185.18.36, Ubuntu 9.10, Thinkpad T61p,
2.6.31-16-generic-pae #52-Ubuntu SMP Thu Dec 3 23:18:13 UTC 2009 i686
GNU/Linux)

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/i686/cmov/libc.so.6
#2  0xb74f8d03 in ?? () from /lib/tls/i686/cmov/libc.so.6
#3  0xb7611fad in system () from /lib/tls/i686/cmov/libpthread.so.0
#4  0xb54cd3e1 in ?? () from /usr/lib/compiz/libcrashhandler.so
#5  <signal handler called>
#6  0xb6b08154 in ?? () from /usr/lib/libGLcore.so.1
#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 :-(
