I think I have the same problem with Alt-Tab.
-------------------------------------------------------------
The first Alt-Tab makes crash compiz but the system respawns it automatically. But the Ubuntu desktop is a bit broken.
The second Alt-Tab (30 seconds later for example) makes crash both compiz and the Ubuntu desktop.
Here is the syslog extract :
