Exception in Xamarin Android Forms (1.3.4) after LoadApplication(new App())

Hi, I'm a complete new starter on Forms but have written regular Xamarin Android projects. I've just created a new Forms (PCL) solution using 1.3.4.

IOS and Winphone both work fine out of the box. Android throws an exception in OnCreate(Bundle) in MainActivity : FormsApplicationActivity. This is also straight out of the box. I've found other posts talking about the same issue, but usually after some navigation action. This is not the case for me, it's on the very first load.

Any help truly appreciated.

Best regards,
Steve Finn
