Can you please install xserver-xfree86-dbg and generate a backtrace with
debugging symbols?

1) # apt-get install gdb xserver-xfree86-dbg
2) answer the debconf questions and make sure XFree86-debug is the
   default X server
3) log in as a normal user
4) $ ulimit -c unlimited
5) $ startx
6) reproduce crash
7) $ gdb /usr/bin/X11/XFree86-dbg core
8) (gdb) bt full
9) cut-n-paste the output from gdb into a mail message to
   170934@bugs.debian.org

Thank you!
