compiz crashed with SIGSEGV in _int_malloc()

[Jake McGregor]

(I am running Ubuntu 12.04 beta) It appears as if this bug was caused by either the ring switcher or the shift switcher in Compiz (I don't remember which one) Whatever it is, it caused the window borders (I think its called gkd-not sure though) to disappear at startup. I had just enough time to fire up the terminal to run the updates, and it seemed to fix some of the problem. It appears as if compiz is restarting every-time I right click, and it doesn't always restart correctly. I suspect this is caused by a faulty Compiz plugin, as I have had similiar issues with that in the pas t with previous versions.
