Crash after suspension

I'm encountering a crash issue after the suspension of the app. To reproduce:

1) Watch live stream (under IIS Smooth Streaming) for at least 4 minutes
2) Lock the device
3) Wait at least 4 minutes
4) Unlock the screen

Frequently, the app crashes or has already crashed during suspension. Found on Surface RT, Acer Iconia and Samsung Ativ.

This does not happen when Visual Studio debugger is attached, thus we have no visibility of the exception throw. Neither a logger help us. The last operation logged is the suspension of the app so it seems that crash occurs there somewhere. Moreover it seems to happen only during live streaming.

My feeling is that some external dll throws an exception (Adaptive Plugin/SmoothStreaming Client/Playready Client....) but I can't understand what's wrong.

Any tip?
