Unauthorized access exception

[LokiMidgard]

I see following in the dashboard

stowed_exception_system.unauthorizedaccessexception_80070005_musicplayer.exe!musicplayer::pages::shellpage::_app_erroroccured_d__11.movenext

unfortunatly I don't have a more detailed stacktrace. I thought this would happen to access an dependency object from the wrong thread, but everything in this should run in the UI thread...

I was able to reproduce it (by accident) on my device. But it can't be reproduced while Debugging.

We actually check where the error seems to occurs if we are in the correct thread, and redireict otherwise. Still It does not work sometimes...
