wheezy upgrade gets 671812: xserver-xorg-core: segfault at exit

[hvw59601 <hvw59601@care2.com>]

Hi,

Dist-upgrading Wheezy is affected by 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671812, when you exit 
from X it segfaults and (in my case?) hangs the system. I ssh'd into the 
desktop and found the backtrace in the log. The bug is closed so it does 
not appear in listbugs.
