Public bug reported: Binary package hint: compiz
As this is a crash in free() I've got no idea whether it is the same as one of the other crashes sorry. Whilst trying to report bug 753047, I was alt-tabbing back and forth between Evolution and Google Chrome. Each time I tabbed away from Evolution everything but the mouse pointer froze for several seconds, followed by all my windows and desktop disappearing then reappearing with a message that compiz had crashed. Reports attached.
