The error I'm experiencing is the same one that's been detailed bellow. I have yet to find any solution that has worked for me.

This error was reported in Xamarin Forms 1.3.1 and here I am dealing with it in 1.4.1
At the entry point of the app, when calling UIApplication.Main(args, null, "AppDelegate")
Stack trace calls are to
Xamarin.Forms.Platform.iOS.PageRenderer.UpdateBackground() followed by
UIKit.UIColor.FromPatternImage(UIKit.UIImage image)
I'm getting a ArgumentNullException on that last one for the parameter "image".
Has anyone else already encountered and resolved this?
