Crashlytics WriteZStream stacktrace

Crashlytics WriteZStream stacktrace

I have a "hard to read" crashlytics log in a real Xamarin iOS application. This problem affects almost 80% of users, and I'm struggling to decrypt it.

Please view gist log

I uploaded the dSYM file to the Crashlytics dashboard, but the log remains the same. Is this log type normal for a Xamarin application?

I don’t even know which application source file is crashing.

I have the following code in AppDelegate.cs:

override public bool FinishedLaunching (UIApplication application, NSDictionary launchOptions){
//...
    Setup.EnableCrashReporting (() => {
                    var crashlytics = Crashlytics.SharedInstance;
                    crashlytics.DebugMode = true;
                    Crashlytics.StartWithAPIKey ("my_key");

                    Fabric.With (new NSObject[]{ crashlytics });

                    AppDomain.CurrentDomain.UnhandledException += AppDomain_CurrentDomain_UnhandledException;
                    TaskScheduler.UnobservedTaskException += TaskScheduler_UnobservedTaskException;
                }, Path.GetFileNameWithoutExtension (typeof(AppDelegate).Module.Name));
}

and the following methods:

    void TaskScheduler_UnobservedTaskException (object sender, UnobservedTaskExceptionEventArgs e)
    {
        var ex = e.Exception;
        Setup.CaptureManagedInfo(ex);
        Setup.CaptureStackFrames(ex);
        Setup.ThrowExceptionAsNative(ex);
    } 

    void AppDomain_CurrentDomain_UnhandledException (object sender, UnhandledExceptionEventArgs e)
    {
        Setup.CaptureManagedInfo(e.ExceptionObject);
        Setup.CaptureStackFrames(e.ExceptionObject);
        Setup.ThrowExceptionAsNative(e.ExceptionObject);
    }
