Same here; Compiz crashed on alt-tab, and my mouse worked but my keyboard became useless. (This might be an artifact of Unity or something?) Manually running Metacity let me log in to post this.
I don't believe Launchpad uploaded my crash report since I marked it as a dupe, but I can send it out of /var/crash if anyone wants it. The exact offending instruction was a bit different:
