Bug description:
  On login, unity-2d-launcher is not running.  Launching a terminal from
  the console and then starting unity-2d-launcher produces the segfault.
  The following output is from gdb:

  (gdb) run
  Starting program: /usr/bin/unity-2d-launcher 
  [Thread debugging using libthread_db enabled]
