To reproduce an error every time, you have to do following:
Open App and start a stream. Press "back" button as often to get to home screen. Now slide down the android-messages-line (whats the correct name for this?). Choose the player. Press "options" button and press stop. The application closes (correct?).
But now the error: Hold after done the above the "home" button for a longer time. The last applications list gets shown. When you choose ServeStream it flashes for a second and nothing open. You can try this as often you like. It always flashes for a second and application never opens.
To open the application again, you have to go into the app-drawer and open it from there.
