[Bryce Harrington <774978@xxxxxxxxxxxxxxxxxx>]

** Description changed:

  [Impact]
  Fairly widespread X crash that occurs seemingly randomly to users, but is actually triggered when a client application makes a call that results in a syndaemon call in the Xrecord module that fails.
  
  [Development Fix]
  Disable linking to the X record module in the synaptics package.  See Robert Hooker's debdiff.
  
  [Stable Fix]
  Same fix as for development.
  
  [Regression Potential]
- 
+ XRecord was not enabled in maverick, so disabling it is not a regression from that version.  It was enabled in natty to permit avoiding polling of the keyboard which presumably might save battery power usage; however it was found to cause widespread bugs shortly after introducing it - see comment #38 for historical discussion.
  
  [Original Report]
  Xserver crashed (landed me back at the gdm login); it happened just after I'd opened a page in firefox - nothing too special, it had some flash in but nothing too unusual and the page reopened fine now.
  
  Seg is in the Xorg.0.log.org
