This problem is probably caused by 154_force-copykeyclass-for-key-events.patch of xserver-xorg-core.

The patch adds
         ChangeDeviceID(mdev, *master);
to CopyKeyClass but doesn't check if master is valid.
Master is NULL in the backtrace, so I guess it segfaults right there.

Luckily there is already a fresh upstream bug report assigned to the patch author:
