ok, then we should move this discussion upstream...
look at this commit: 
http://gitweb.freedesktop.org/?p=xorg/app/compiz.git;a=commit;h=256882741efef0dfc583304fe672045281a12895

I don't know exactly what has fixed it upstream.. I will test it 
tomorrow again, and try to get a backtrace, the problem is that it isn't 
easy to reproduce, sometimes it happens after some minutes sometimes it 
works for hours with no problems.
as for current git, it never happend for me...

ok but 0.4 should be out before F7 final so I hope this makes it in.
