Programmatically dismissing a UIAlertView on iOS 5 doesn't call didDismiss delegate method

Question

I'm running into a problem where 9 times out of ten, when I call UIAlertView's dismissWithClickedButtonIndex:animated:, the delegate method alertView:willDismissWithButtonIndex: is not called. Is anyone else running into this problem? I'm about to file a bug with Apple but I'm curious to see if anyone else has run into this issue and figured out any workarounds.

To ensure a consistent behavior across iOS4 and 5, you could just remove the UIAlertView's delegate just prior to calling its dismissWithClickedButtonIndex:animated: method, then manually invoke the delegate method. e.g.

- (void)somethingDidHappen {
    id<UIAlertViewDelegate> delegate = myAlertView.delegate;
    myAlertView.delegate = nil;
    // now, we know the delegate won't be called...
    [myAlertView dismissWithClickedButtonIndex:0 animated:NO];
    // ...so we call it ourselves below
    [delegate alertView:myAlertView clickedButtonAtIndex:0];
}

(That code isn't tested, but you get the point.)
