Jerry,
If you still have that crash file, install unity debug symbols (see https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages) and do:
apport-unpack /var/crash/_usr_bin_compiz.1000.crash /tmp/unity-crash
Then: gdb /usr/bin/compiz /tmp/unity-crash/CoreDump
At this point, do: bt full
And post the output here
