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.
