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:

SegvAnalysis:
