Perhaps a dupe of bug 1490698?

Yes, it looks like a dupe of bug 1490698. I have already attached the patch for it. I will keep monitoring this bug to check if the patch of bug 1490698 resolves the problem or not.

Although I think the crash signature is the same with bug 1490698. Now bug 1490698 is checked in, let see if it influences this bug, too.

Duping to Bug 1490698. The crashes seemed to have ceased following the 9-14 fix for that bug.
