Bug#497116: xorg: random crashes on shutdown

No ping after a crash. trying to ssh into the system (it works before a crash)
results in:
$ ssh mheinzes@160.129.138.82
ssh: connect to host 160.129.138.82 port 22: No route to host

I installed those packages and opened a ssh connection after booting, attached
gdb and continued.
When shutting down KDE detects the running ssh session, and asks about closing
them. If I confirm that, I get the gdb messages about receiving SIGTERM,
SIGHUP, and SIGCONT, which I continue on.
In case of a crash the system stopps working after one of those messages, see
attached crash.txt. If everything works Xorg exits normally and I get no-
crash.txt, attached as well.
This information does not seem very useful to me, but I am glad if I can help
more. So, please tell me.
