Try a global Error catch and see what it produces.

 public partial class App : Application
    {   
        [STAThread]
        public static void Main()
        {
                var application = new App();

                application.DispatcherUnhandledException += 
                    new DispatcherUnhandledExceptionEventHandler(application_DispatcherUnhandledException);

                application.InitializeComponent();
                application.Run();
        }

        static void application_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
        {
            LogAndClose("Global exception: " + e.Exception.ToString());
        }

        public static void Log(string text)
        {
            try
            {
                System.IO.File.AppendAllText(Environment.CurrentDirectory + "\\Log.txt",
                    "[" + DateTime.Now.ToString("MM/dd/yy HH:mm:ss") + "] " + text + "\r\n");
            }
            catch { }
        }

        public static void LogAndClose(string text)
        {
            Log(text);

            try
            {
                Application.Current.Shutdown();
            }
            catch { }
        }
    }
