Bug#712545: Bug severe: Updated X crashes immediately after loading

[Pat Parson <parspes@gmail.com>]

Package: xserver-xorg
Version: 1:7.7+7
Followup-For: Bug #712545

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
Updated Xorg using aptitude to latest testing branch. 
Upon restarting lightdm the Xserver crashes after loading the initial 
GTK-greeter screen, then reloads repeatedly which makes it impossible 
to login to the machine without rebooting into recovery mode.
