Once bug 500402 is fixed, this will definitely be an issue, but I wonder whether it's possible to call imgContainer::Draw() on animated GIFs that haven't been decoded yet. If so, and we're currently at a frame that hasn't been composited, we'll try to draw a paletted image directly, which isn't possible. I don't think this is actually an issue currently, though, because if Notify() hasn't been called, then we're by definition at the first frame, which is in ARGB format (at least until bug 527081 happens).
Without anything else to go on, I don't think this is actually an issue.
