title: Xamarin app crashes on startup on device, works fine in simulator
body: <p>Would appreciate any suggestions, using SDK6.1 with Xcode 5 on OS 10.8</p>
  
  <p>The app crashes right after the splash and does not get to the debugger at all. this happens on the TestFlight released version as well. Tried on another computer with same results. Even tried to create a new sample Monotouch app and same results.</p>
