When the X server crashes, the problem is actually located in
xserver-xorg-core (reassigning the bug). I assume you were running
xserver-xorg-core 2:1.1.1-19 or so ? Could you try xserver-xorg-core
currently in experimental (2:1.2.99.901-1) ?

I'd be great to have a backtrace with debugging enabled, by rebuilding
the X server and attaching a gdb. It might be boring to do if the bug is
not easy to reproduce. But, in case you want to try, you can rebuild with:

	DEB_BUILD_OPTIONS="nostrip noopt" fakeroot apt-get -b source xserver-xorg-core


and attach gdb with:

    gdb -p $(pidof X)

thanks,
