compiz crashed with SIGSEGV in _M_release() - getCompPluginVTable20090315_unityshell() [xserver 1.14]

[Bryce Harrington]

Installed the new X stack from canonical-x/x-staging, rebooted, and found that compiz crashes on logging in (the unity-greeter session seems fine). I restarted lightdm and re-logged in a second time and hit the same problem.

I had updated the system just prior to installing x-staging, and I don't think there's been any other changes, so am guessing the change in the X stack is what led to the crashing. Guessing this is due to the pointer barrier changes that will need updated in unity (for which work is already under way.)
