compiz crashed with SIGSEGV in free()

[Rostislav Dzinko]

Crashed when I ran command: "unity --replace" from tty2. I had to do that because unity didn't start on login.

Sadly apport did not get a good trace from your crash. Is this something that happens regularly or did it just happen this one time?

[Rostislav Dzinko (rostislav-dzinko)]

This happened only once so I'm afraid I've got nothing to help you with.
