Bug Description

Compiz seg faults every time I login. When I login I get my back ground and some notify-osd notifications but nothing else. If I drop to a VT and run `DISPLAY=:0 unity --replace`, switch to VT7 (nothing has changed really) and back to VT2 I see in the output that compiz has crashed with a segmentation fault. Hopefully the attached crash file will help. I just did a dist-upgrade and rebooted, so should be completely up to date.

Crash occuring only if there is no opened windows. After opening some application unity starts normally, but crashing again if all windows closed.
