Compiz crashes when enabling or disabling a plugin in ccsm

Binary package hint: unity

When enabling or disabling a plugin in ccsm compiz crashes. This does not appear to be bug #682345 as the backtrace is quite different.

Restarting compiz works, and the new state of the enabled/disabled plugin is correct (ie: if compiz crashed while enabling the plugin, on restart the plugin will be enabled).

Backtrace attached.
