Forgot to mention that I also tried to connect the gestureRecognizers outlet of the UIImageView to the gesture recognizer, making sure the one from the scrollview had been removed with same result….

So, I have an Xcode 4.4 iOS 5.1 project using ARC with a UITableViewCell that contains a UIScrollView, among other things, which scrollview contains an UIImageView. I want the user to be able to zoom the image view, obviously. So, I dragged an instance of UIGestureRecognizer into my controller's segue (scene?). I then connected its action to an action method in my view controller. I then dragged a connection from the scrollview to the gesture recognizer and connected it to the gestureRecognizers of the scrollview. Everything seems to be OK. But when I launch my app in the simulator, as soon as the view is to appear, it crashes more or less randomly with:
