Since then the X server has already crashed 5 times, which renders the system close to unusable for me.

The relevant messages for the three crashes from today can be found at: Oct 28 15:56:36 Oct 28 12:06:58 Oct 28 09:08:51 Unfortunately I have no clue how to reproduce the segfault. The last crash happened while I was reading some document and I did not push any button, moved the mouse or anything...
