Byron, is this fall out from your mtransport refactor?
Flags: needinfo?(docfaraday)
Possibly. I'll look into it.
No, this bug has been there all along, although my monkeying around with the TransportFlow stuff might have altered the timing enough to make it happen more often.
Flags: needinfo?(docfaraday)
Specifically, the bug is that we are unsetting MediaPipelineReceiveVideo::mListener on main, before STS is done using it.
Comment on attachment 8989240 [details] Bug 1471697: Stop unsetting mListener on main. https://reviewboard.mozilla.org/r/254292/#review261156 Looks good to me.
