UIAlertView TextBox first responder crash

Description of Problem:
When creating a custom UIAlertView that has a text field to collect some
information, ResignFirstResponder is used in the text fields ShouldReturn
callback.  This causes the app to exit without any message at all.

Steps to reproduce the problem:
            UITextField tf = new UITextField(new System.Drawing.RectangleF
                                             (12f, 45f, 260f, 25f));
            tf.BackgroundColor = UIColor.White;
            tf.UserInteractionEnabled = true;

            /***** This is what causes the crash *****/
            tf.ShouldReturn = (x) => {
                x.ResignFirstResponder ();
                return true;
            };

            //tf.ShouldReturn = DoReturn;

            UIAlertView myAlertView = new UIAlertView
            {
                Title = "Give the text box focus",
                Message = "This should be hidden..."
            };

            myAlertView.AddButton("Cancel");
            myAlertView.AddButton("Ok");
            myAlertView.AddSubview(tf);
            myAlertView.Show();


Actual Results:
Application exits without warning when selecting the text box.

Expected Results:
Alert Dialogue appears that allows users to enter text and when they select
return on the keyboard, the keyboard should disappear.

How often does this happen? 
Everytime
