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.
