This seems to happen fairly often (3 times since LSan landed), and we probably don't care a huge amount about an XML parser leak, so I think I'll land a suppression for it and then turn this into a bug for fixing the leak. Annoying the sheriffs has no value. The stack in comment 0 is all the information we have.

The last one is a new leak. I filed bug 1034602 for it.
I'm removing the intermittent failure tag from this, as it shouldn't happen any more due to a suppression, but there's still a leak that could in theory be fixed.

Some instances of this are getting annotated as bug 1166041.

FYI, I did a recent Try push with this suppression removed and all the occurrence I hit were in toolkit/components/thumbnails, in case that helps pin down where the problem is.
