Comment (by arlolra):

 > This error appears to occur *after* OnIceComplete() is fired, meaning
 that in the proxy-go code:

 Ah, so it is a bug in go-webrtc to assume `iceComplete`, when only
 `iceGathering` has completed,
 https://github.com/keroserene/go-
 webrtc/blob/master/peerconnection.go#L518-L522

 > It's also worth pointing out that apparently OnICECompletel is being
 deprecated (​peerconnection.go#L518) we are better off not relying on it
 anyway.

 If that's the case, we should remove it there too.
