Bug description:
  [Test Case]
  Crash fix, just verifying that the crash does not happen anymore. No clear test case.

  [Regression Potential]
  Visual regressions at most.

  Original description:

  Ubuntu 12.04 as of April 16, 2012: I use CCSM to set a trigger for
  Expo reveal to top right edge. More often than not it seems compiz
  crashes on login, leaving a nautilus-only desktop. Restarting lightdm
  from a VT then logging in again usually fixes it, but at that point
  Compiz loses my Expo hot corner. It still remains set in CCSM, but I
  have to unset then re-set it for it to work.

  This used to happen a lot in Ubuntu 11.10 as well.
