[Bryce Harrington <774978@xxxxxxxxxxxxxxxxxx>]

** Description changed:

- Binary package hint: xorg
+ [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.
  
- 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.
+ [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]
+ 
+ 
+ [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
