May be a MediaStreamTrack issue, but don't know the appropriate component.

[Randell Jesup [:jesup] (needinfo me)]

->jib to look at

Comment 4

[Randell Jesup [:jesup] (needinfo me)]

From debugging: this is the source of the nullptr that leads to the assert:

/home/jesup/src/mozilla/inbound/dom/media/DOMMediaStream.cpp:

already_AddRefed<Promise>
DOMMediaStream::ApplyConstraintsToTrack(TrackID aTrackID,
                                        const MediaTrackConstraints& aConstraints,
                                        ErrorResult &aRv)
{
  return nullptr;
}

This is too late to fix in 43 but I'll track it in case it becomes a bigger problem on release.

Thanks for catching that. Just missing a test, otherwise good to go.
