XNA Zune HD app won't come out gracefully

I have both built and deployed an app created with a new project template for zune hd. The problem is that whenever the app exits, the Zune reboots. This happens when debugging remotely from a PC or when used correctly from a device. This happens both in debug mode and in release. I've included some basic template code, but it's pretty generic. Does anyone have any idea?

public class DrawGame : Microsoft.Xna.Framework.Game
{
    private GraphicsDeviceManager m_graphics;
    private SpriteBatch m_spriteBatch;

    public DrawGame()
    {
        m_graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";

        TargetElapsedTime = TimeSpan.FromSeconds(1 / 30.0);
    }

    protected override void Initialize()
    {
        base.Initialize();
    }

    protected override void LoadContent()
    {
        m_spriteBatch = new SpriteBatch(GraphicsDevice);
    }

    protected override void UnloadContent()
    { }

    protected override void Update(GameTime gameTime)
    {
        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
        {
            this.Exit();
        }

        base.Update(gameTime);
    }

    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        m_spriteBatch.Begin();
        m_spriteBatch.End();

        base.Draw(gameTime);
    }
}
