MyToolkit You Tube API. Video Player Crash in windows phone 7

Question

I'm trying to create and app with inbuilt capability to watch You tube videos. The plugin that I am using to implement this feature is "MyToolKit"(http://mytoolkit.codeplex.com/). The whole thing works fine. When the request query is sent to the API, the videos and thumbnails appear correctly. But when selected a specific movie, an exception is thrown and Visual Studio breaks to the debugger. The following is the code at the Video Selection point.

private void Grid_Tap(object sender, System.Windows.Input.GestureEventArgs e)
        {
            Grid tappedGrid = sender as Grid;
            YouTubeVideo selectedVideo = tappedGrid.DataContext as YouTubeVideo;
            string videoId = selectedVideo.YouTubeVideoId;
            try {
                YouTube.Play(videoId, YouTubeQuality.Quality480P, e1 => { if (e1 != null) { MessageBox.Show(e1.Message); } });
            }
            catch(Exception e1){
                MessageBox.Show(e1.Message.ToString());
            }

           // MessageBox.Show(videoId);
        }

The exception is thrown and the debugger breaks into the application generic exception(App.xaml.cs) Although the exception is handled as shown above, which i thought is the place at which the exception occurs. Hence the debugger/app crashes. The video continues to play at the Default Video Player. Any suggestions on how to solve this?.

Unless you're doing anything with Page.State or Application.State or other serialization on navigation it looks like an issue with the library you're using. Raise with them.
