nsHTMLCanvasElement::GetContext creates a hash property bag to convert its context options into an nsIProperties object. Unfortunately a hash property bag has inherits multiply from nsIProperties and the wrong one gets put in the second nsCOMPtr. (I'm not sure why it uses two nsCOMPtrs in the first place.)
I've been meaning to file this for some time, thanks for doing that.

Looks fine to me. Benoit should probably look, but I think it's fine for his review to come after landing.
