title: App crash when running on iPhone 4.3 simulator after calling initWithNibName
body: <p>I have the following code associated with pressing a button:</p>
  
  <pre><code>- (IBAction)favorites
  {
      FavoritesActivityViewController *favorites = [[FavoritesActivityViewController alloc]     initWithNibName:@"FavoritesActivityViewController" bundle:[NSBundle mainBundle]];
      [self.view addSubview:favorites.view];
  }
  </code></pre>
  
  <p>When I run it on my iOS device (v 6.1) it works fine but when running on the 4.3 simulator it crashes when getting to calling addSubView. I have noticed that it crashes for any method I call on self.view like setTag etc so I guess the problem is with the returned object from initWithNibName</p>
  
  <p>Thanks,
   Simon</p>
