How the ... We're trying to AddRef something with a negative ref count.

I'm gonna file this under suspected memory stomping like what we're seeing in bug 1306856.

[Byron Campen [:bwc]]

Hmm. A quick look around makes me a little nervous about VideoFrame::mImage, particularly VideoFrame::GetImage(), which returns a bare pointer, and is called from lots of places. If any of these places races against functions that reset mImage (VideoFrame::SetNull() and VideoFrame::TakeFrom()), bad stuff can happen quite easily, including invalid ref counts. I don't really know what thread calls what though.
