Title:
Xorg crashes with segfault on 15.10
Status in xorg package in Ubuntu:
New
Bug description:
I updated my system from 15.04 to 15.10 yesterday. Since then the X
server has already crashed 5 times, which renders the system close to
unusable for me.
The corresponding messages in Xorg.0.log.old are:

I have attached the syslog file. The relevant messages for the three crashes
from today can be found at:

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...
