Bug#416444: xserver-xorg: crash, maybe font related
Does this problem still occur with the latest release of Xorg packages
that are currently in unstable, I mean at least xserver-xorg-core 1.3?
If so, we really need a backtrace of the crash. You should have one at
the end of Xorg.0.log right after the crash (or in Xorg.0.log.old if you
already restarted another server). A better backtrace may be obtained by
attaching gdb *through ssh* first with
gdb -p $(pidof X)
and entering "bt full" once the crash happened.
