title: UIBarButtonItem in UiToolbar not responding to touch, only in ios7 portrait mode
body: <p>I'm updating an existing app for iOS7. The app uses a UIToolbar with two UIBarButtonItem's, one on the left, the other on the right.</p>
  
  <p>The left UIBarButtonItem works as expected. The right UIBarButtonItem does also, <em>except</em> in landscape orientation on iOS7. It works fine in iOS6 (all orientations), and in portrait mode (only) in iOS7. I'm seeing this in both the simulator and on my iPad mini.</p>
  
  <p>The button is obviously correctly bound to a segue (since it usually works), and I have confirmed that it is enabled even when it is not working. (My view controller has an update timer, and I log the state on every tick.)</p>
  
  <p>Has anybody else seen something like this? Any ideas?</p>
  
  <p>TIA,
  Doug K;</p>
