title: '+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil' (Cocos2D)
body: <p>Xcode 3.2.5, iOS 4.2 (Simulator), Cocos2D 0.99.5</p>
  
  <p>Following <a href="http://www.oscarvgg.com/your-first-game-in-cocos2d-part-1-menus-and-transitions/" rel="nofollow">this tutorial</a> comes with a wonderful crash, as seen below.</p>
  
  <p>I haven't found a single (directly) relevant thing through Google on any site. The closest I got was something else on this site with the same error, but a completely different reason. (I assume so, anyway. But then, given that 0.99.5 comes with two Analyzer results, it could just be a bad release…)</p>
