q("[onpeerconnectionfail]"), this.trigger(new D.PublisherEvent(D.PublisherEventTypes.PUBLISH_FAIL, this)), this._subscriptionResolver.reject("Peer Connection Failed.");

this._subscriptionResolver can be undefined in scenarios where the offer is send but never receive an answer (this can be reproduced using a firewall to block outgoings)
