title: [UILabel copyWithZone:]: unrecognized selector sent to instance
body: <p>I feel like I'm banging my head against the wall here (and I'm ready to do that, frankly).</p>
  
  <p>I'm trying to set a background to the view.  Background I need to set is an image and I'm using this code (which works perfectly fine in two other UIViewController subclasses - this was a copy/paste into the new file):</p>
  
  <pre><code>UIImage *img = [gameNode imageFromKey:@"background"];
  UIColor *bg = [[UIColor alloc] initWithPatternImage:img];
  self.view.backgroundColor = bg;
  [bg release];
  </code></pre>
  
  <p>As I said, this works perfectly fine in two other places, however here, line <code>self.view.backgroundColor = bg</code> throws</p>
  
  <pre><code>'NSInvalidArgumentException', reason: '-[UILabel copyWithZone:]: unrecognized selector sent to instance 0x9259840'
  </code></pre>
  
  <p>There's not much more to go by.  I verified in IB that the top-level view's referencing outlet is set to the File's owner.  I cleaned the project and restarted.  I even closed Xcode and restarted it again - no luck.  What else am I missing?</p>
  
  <p><strong>Edit:</strong>  As I mentioned, there's not much back stack trace, just this:</p>
