** Description changed:

  [Impact]
  Crashes the X.org server for some people several times a day.
  
  [Test Case]
  1. Start Xephyr
  2. killall Xephyr
  Broken Behavior: Aborts with SIGSEGV and a backtrace
  Fixed Behavior: Exits cleanly
  
  [Regression Potential]
- Will regress LP #968845 so more work needs to be done on that.
- Since this is effectively a rollback to 2:1.11.4-0ubuntu10.1
- I expect no further side effects.
+ Reverting the patch from 10.2 will regress LP #968845,
+ but adding patches from the X-server git tree seems to
+ fix the issue. Any xserver bug reports will have to be
+ watched closely, especially if they mention suspend/resume.
+ The x server git tree will have to be watched as well,
+ in case any fixes/crashes related to the code are fixed there.
