Bug description:
  I was running CCSM, (trying to fix things up after 'unity --reset' was
  not my friend).  I went to Preferences, the 'unity' profile was
  selected, and I hit 'reset to defaults'.  Compiz crashed as above.

  (I ended up running
     dconf reset -f /org/compiz/profiles/unity/
  to get back to what I hope is a properly set-up unity.  I hope not to touch ccsm for a while, nor hit this bug again.  So if I'm lucky, this crash is not an ongoing issue as far as I'm concerned.)

  Thanks.
