Ami did some detective work in bug 89733, comment 8 and got the following stack:

Looking at the code, I'm not sure why we're trying to update the layout during paint.  That seems wrong.  My random guess would be that we can just remove the call to updatePlayer since RenderVideo::layout has already called it at this point.
