I'm developing an app in Xamarin iOS and Android. In a few case the iOS version (not android) report trough bug report system this problem:

I don't understand if this is a problem of Mono/Xamarin or can be my code.

Any idea?

UPDATE As request in the comment this is the code of Main

public class Application
    {
        // This is the main entry point of the application.
        static void Main (string[] args)
        {
            Xamarin.Insights.Initialize ("xxxxxxxxx"); //id of the app on insight
            UIApplication.Main (args, null, "AppDelegate");
        }
    }

And this is my AppDelegate

    [Register ("AppDelegate")]
    public class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations

        public override UIWindow Window {
            get;
            set;
        }

        public static UIStoryboard Storyboard = UIStoryboard.FromName ("TouristAppStoryBoard", null);
        public static UIViewController initialViewController;

        public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
        {

            Window = new UIWindow (UIScreen.MainScreen.Bounds);

            initialViewController = Storyboard.InstantiateInitialViewController ();
            Window.RootViewController = initialViewController;

            var navController = Window.RootViewController as UINavigationController;
            navController.NavigationBar.TitleTextAttributes = ViewUtility.GetAttributesForTitleNavigationBar ();

            Window.MakeKeyAndVisible ();
            return true;
        }

        public override void OnResignActivation (UIApplication application)
        {
        }

        public override void DidEnterBackground (UIApplication application)
        {

            LocationManager.GetIstance ().StopLocationUpdates ();
            var taskID = UIApplication.SharedApplication.BeginBackgroundTask( () => {});
            Task.Factory.StartNew ( () => {
                ComuniDb.GetIstance().Manutenzione();
                UIApplication.SharedApplication.EndBackgroundTask(taskID);
            });
        }

        public override void WillEnterForeground (UIApplication application)
        {    
            LocationManager.GetIstance ().StartLocationUpdates ();
        }
    }
}

My app it's not little, I hope you find what you are looking for.

I found the problem. The problem is logged in the device log, but not in the crash log. It's silly for me (device log has more information than crash log?), but I found the bug and fix it.
