Status changed to 'Confirmed' because the bug affects multiple users.

Hello cliff, or anyone else affected,

Accepted unity into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

since applying the update CCSM occasionally freezes when enabling a
plug-in and will crash the desktop I can still get to a console (ttty3)
where I have tried restarting lightdm and restarting the X-server and
compiz, sometimes sudo restart lightdm does get the desktop going again,
but usually I have to sudo reboot.
After rebooting the plugin seems to work but when I try to enable or
disable anything it freezes again and I end up having to reboot again.
so mixed results so far
