title: Could not insert new action connection Error
body: <p>I get this error, when try to create new action for UIButton by dragging blue arrow from UIButton to my header file (you know, this new feature of XCode 4...)</p>
  
  <p>When I create action in code by myself and connect it in old way, simply by dragging from button to File's Owner, it's works well</p>
  
  <p>Here's screenshot:
