App crashes with "Termination Reason: Namespace Codesigning, Code 0x1"

Hi there,

as soon as I add a provisioning profile to the "Mac Signing" settings in xamarin studio the app crashes with "Termination Reason: Namespace Codesigning, Code 0x1". If I don´t add a provisioning profile it works but to deploy it to the mac store it will add it to the pkg-file and then the app crashes again so it will get rejected.
I think that I did everything from https://developer.xamarin.com/guides/mac/deployment,_testing,_and_metrics/publishing_to_the_app_store/ and I don´t know how to solve that problem.
Am I missing something here?

Thanks,

Benjamin
