Double call "onGetUserMediaSuccess" and "createAnswer". Sipml5 can't answer on some calls and sends BYE. about sipml5 HOT 4 OPEN

I research this flying trouble and  make hack-patch for it. Test in 
Chrome-Chrome , Chrome-FF, FF-Chrome p2p call.

tmedia_session_jsep01.onGetUserMediaSuccess = function (o_stream, _This) {
    tsk_utils_log_info("onGetUserMediaSuccess");
    var This = (tmedia_session_jsep01.mozThis || _This);
    if (This && This.o_pc && This.o_mgr) {
        if(!This.b_sdp_lo_pending){
            tsk_utils_log_warn("onGetUserMediaSuccess but no local sdp request is pending");
            return;
        }

     if(This.my_mutex){tsk_utils_log_warn("onGetUserMediaSuccess already executed!"); return;}
     This.my_mutex=true;

        if (o_stream) {
            // HACK: patch for Firefox and others
            // https://groups.google.com/group/discuss-webrtc/browse_thread/thread/e30f0ffc267bce5f
            if (!o_stream.videoTracks || !o_stream.audioTracks) {
                var b_support_audio = !!(This.e_type.i_id & tmedia_type_e.AUDIO.i_id);
                var b_support_video = !!(This.e_type.i_id & tmedia_type_e.VIDEO.i_id);
                o_stream.audioTracks = o_stream.getAudioTracks ? o_stream.getAudioTracks() : { length: b_support_audio ? 1 : 0 };
                o_stream.videoTracks = o_stream.getVideoTracks ? o_stream.getVideoTracks() : { length: b_support_video ? 1 : 0 };
            }

            // save stream other next calls
            if (o_stream.audioTracks.length > 0 && o_stream.videoTracks.length == 0) {
                __o_jsep_stream_audio = o_stream;
            }
            else if (o_stream.audioTracks.length > 0 && o_stream.videoTracks.length > 0) {
                __o_jsep_stream_audiovideo = o_stream;
            }

            if (!This.o_local_stream) {
                This.o_mgr.callback(tmedia_session_events_e.STREAM_LOCAL_ACCEPTED, this.e_type);
            }

            // HACK: Firefox only allows to call gum one time
            if (tmedia_session_jsep01.mozThis) {
                __o_jsep_stream_audiovideo = __o_jsep_stream_audio = o_stream;
            }

            This.o_local_stream = o_stream;
            This.o_pc.addStream(o_stream);
        }
        else {
            // Probably call held
        }
        This.o_mgr.set_stream_local(o_stream);

        var b_answer = ((This.b_sdp_ro_pending || This.b_sdp_ro_offer) && (This.o_sdp_ro != null));
        if (b_answer) {
            tsk_utils_log_info("createAnswer");
            This.o_pc.createAnswer(
                tmedia_session_jsep01.mozThis ? tmedia_session_jsep01.onCreateSdpSuccess : function(o_offer){ tmedia_session_jsep01.onCreateSdpSuccess(o_offer, This); },
                tmedia_session_jsep01.mozThis ? tmedia_session_jsep01.onCreateSdpError : function(s_error){ tmedia_session_jsep01.onCreateSdpError(s_error, This); },
                This.o_media_constraints,
                false // createProvisionalAnswer
            );
        }
        else {
            tsk_utils_log_info("createOffer");
            This.o_pc.createOffer(
                tmedia_session_jsep01.mozThis ? tmedia_session_jsep01.onCreateSdpSuccess : function(o_offer){ tmedia_session_jsep01.onCreateSdpSuccess(o_offer, This); },

Wow, guy, that's just the solution I were looking for, and just the time it was 
about to hit the fan!
Problem with sipml5 + chrome 40-41 + asterisk 11.15-11.16.

I'd gladly buy a chicken and sacrifice it for deity of your choice.

What do you think will be this patch-update in the next official release?

We rolled back to the stable version 1.4.217. But most likely we need the 
additional support for the FF browser. Looking forward to the FF-36 release, 35 
doesn't work for us.

In any case, thank you for support and answers in this post!
