Looking at the dependencies, mesa could be upgraded too...

Could you ssh from another machine and attach gdb to X before starting
compiz ? (with "gdb -p $(pidof X)")
If would be great to do this with a server recompiled for debugging. If
you want to do so, see how to build at
http://wiki.debian.org/HowToGetABacktrace (with hello=xserver-xorg-core).
