Public bug reported: Might be similar to bug 902787, but I do have composite enabled so therefore filing a new bug. I just installed 12.04 beta 2 today (fresh install), updated it and after a reboot I was just working with SC to re-install my apps using the nifty 'Sync Between Computers' option, when suddenly SC exited and the entire UI froze (however, the mouse cursor kept on working). Could not even switch back to terminal using CTRL-Alt-F1.
Only a hard reset remained. Fortunately, apport has been much improved an promptly asked me to file this bug. So here you go.
