This seems like a duplicate of bug 418779 to me.
Reporter, could you try out the latest nightly trunk build to see if it still crashes for you?

Ok, thanks for testing, let's call this a duplicate of bug 418779 then.

This was fixed in 423270 and the stack there is the same.

Bug 418779 has a slightly different stack and hasn't been confirmed fixed yet.
