Compiz hung while I was working

[Stuart Langridge]

Binary package hint: compiz

I'm running 11.04 with dual screens, and started ccsm to enable the zoom plugin. After going "back" from the Enhanced Zoom configuration screen (I had changed nothing), compiz hung. I have attached a backtrace from gdb'ing compiz.
