If compiz/unity is hanging then next time it happens, please switch to tty1 (Ctrl+Alt+F1) and run this:
gdb /usr/bin/compiz `pidof compiz` | tee ~/gdblog.txt
Then in gdb, do this:
thread 1
bt
Now kill/restart compiz as before and attach the resulting file "gdblog.txt" (in your home directory) to this bug.
