Problem with Master/Detail view in Xamarin.Forms 1.5.0

Hello!

We use a master-detail view in Xamarin Forms and so far it worked on Android and iOS. Since the last update (Xamarin.Forms 1.5.0) the iOS version throws an exception when changing the MainPage (the Android code still works):

System.Linq.Check.Source (source=(null)) in 
/Users/builder/data/lanes/2077/d8e9592a/source/maccore/_build/Library/Frameworks/Xamarin.iOS.framework/Versions/git/src/mono/mcs/class/System.Core/System.Linq/Check.cs:38

Xamarin.Forms.Application.set_MainPage (value={Test.Mobile.RootPage}) in 
Test.Mobile.App.ShowRootPage (ctrl={Test.API.Model.ControllerModel}, showMenu=true)

Any hint what could have happened?
