Could be related to the upstream bug
    https://bugs.freedesktop.org/show_bug.cgi?id=12414

Could you try to get a backtrace with debugging symbols? You'll have to:
* install xserver-xorg-core-dbg
* login from another machine with ssh
* attach gdb to X before starting windowmaker with "gdb -p $(pidof X)"
* start windowmaker and let the crash occur
* enter "bt full" in gdb to get the nice backtrace

Thanks,
