Comment 11 for bug 375896

There are two new bugs that appear similar to this one -- Bug 433504 (recently resurrected) and Bug 644025. Inspection of their stack traces reveals the apparent similarity. I don't think they're duplicates of this...but in case they are, or the similarity is otherwise useful to fixing them, I'm posting here to indicate the possible relation.

(I've already commented on those bugs to indicate this.)
