Still happens on trunk.

There are a bunch of places that we could fix this assertion... I don't know where the right place is though, and the code deals with not having a script global object well enough. Basically JS urls assert that they can get an SGO. When they can't, they bail, and because the video code loads the URL on an event, the SGO is NULL by the time the JS URL starts to load.

First testcase doesn't reproduce anymore for me on trunk, but the second one does still.
