How can I get more information about unhandled exception?

I just use Navigation.PopModalAsync() method to return the previous page. It returns. But if I tapped something I take this exception.
I compile this project for Android (4.0.3 support). Exception occur in Android 4.0.3. In Android 4.3 all is good. Maybe, the first device does not have enough system parameters (memory, CPU).. idk)

This part in Debug seems suspicious. But it nothing says to me..
