iOS 7 bug or my bug in UIAlertView

Question

I have got the following stack trace while my app crashes on tapping "OK" on a UIAlertView. Is it my fault or a iOS7 bug? I don't know how to fix this.

Alert view code

UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Error"     message:[NSString stringWithFormat:@"Es ist ein Fehler aufgetreten: %@", [error localizedDescription]]     delegate:self     cancelButtonTitle:@"OK"     otherButtonTitles:nil]; [av show]; 

and I haven't defined a delegate method.

Stupid me, I just have to set the alert view's delegate to nil
