Backtrace of xorg process when hanging

Sometimes when I close a window, Xorg hangs and I cannot interact with the machine anymore (mouse pointer can still be moved, but no input, be it via mouse or keyboard is accepted). Logging in remotely in such a case revealed that the xorg process uses 100% CPU.

System information:

radeon driver 6.10 on an ati radeon mobile x 1400
xorg 7.4 on ubuntu intrepid
compiz 0.7.8

Will attach a backtrace, hope that helps. I haven't found any action that triggers the hang, it just happens maybe once a week.
