Title:
  unity SEGFAULT on startup

Status in Unity:
  Expired
Status in “unity” package in Ubuntu:
  Expired

Bug description:
  up-to-date Ubuntu 13.04 with optimus card (intel & nvidia gt 640m)

  What should happen:
  Unity launches after entering password in ldm.

  What really happens:

  clickable desktop (with icons) appears without unity topbar or
  launcher

  upon lauching TTY1, and running unity manually, unityshell segfaults

  Thinking it was related to my video card, after tinkering the system
  for a few days, I ended up purging nvidia and bumblebee. I reinstalled
  nouveau and later replaced nouveau with nvidia-304 and bumblebee. The
  system works fine except unityshell that still segfaults, even after
  trying the one in daily ppa.

  What info do you need to debug this?

  Cheers
