Bug Description

When I switch from one virtual desktop to another using the keyboard (i.e. ctrl-alt-left), sometimes it freezes and the X become completely irresponsive. I have to go to the console and kill metacity in order to recover it.

This is the backtrace I get if I attach to the metacity process once it hangs:

(BTW, is there any package containing the debugging symbols for metacity?)
