Thanks for your bug report. Is this still an issue for you? Since this issue was reported there have been a lot of changes in compiz code base and also the stacktrace in this bug report is not useful either. If you still face this crash please try to get a backtrace by following the instructions here <https://wiki.ubuntu.com/Unity/FilingBugs#Getting a stack trace>

Please ignore the last link, you need to get a Valgrind log by following these instructions https://wiki.ubuntu.com/Valgrind
