Title:
  SEGV in libunityshell.so/LauncherIcon::GetQuirk(LauncherIconQuirk)
  during update

Status in Unity:
  Fix Released
Status in “unity” package in Ubuntu:
  Fix Released

Bug description:
  During a daily upgrade using 'update-manager' I got the following
  unity crash (I happened to have unity running under gdb in a screen
  session).  I believe it was during update-manager doing installation
  of one of the gstream packages, but I didn't note it down exactly.

  unity=3.2.2-0ubuntu2 is the /current/ version according to dpkg, so if
  that changed during upgrade it would have been the previous version of
  unity.

  Program received signal SIGSEGV, Segmentation fault.

  (Apologies if this is a dup I have a feeling I've seen something
  similar, but nothing pops up from grepping)
