Yeah, given the backtrace below, we need a better backtrace to identify
and report the exact problem. You should install xserver-xorg-core-dbg,
attach gdb to the X server, reproduce the crash, enter 'bt full' in gdb,
and send us the whole output.
The easiest way to do that is to login from another machine with ssh,
and attach with 'gdb -p $(pidof X)'.

It could be bug #446452.
