The following crash bypassed the Mozilla crash reporter. http://people.mozilla.org/~kbrosnan/x64-dump/ I don't have x64 WinDebug installed at this time. So I can't get a stack at this time. Will follow up on this later.

Kevin, do you still get this crash?
No idea. It was just a dump for someone to look at. I guess no one had the time.
