title: NSBundle pathForResource returns nil with subdirs
body: <p>I have a bunch of directories and files in my app, for instance <code>images/misc/mainmenu_background.</code>. I'm running the following code in the "iPad Simulator 3.2":</p>
  
  <pre><code>NSString *images = [[NSBundle mainBundle] pathForResource:@"images" ofType:nil];
  NSString *images_misc = [[NSBundle mainBundle] pathForResource:@"images/misc" ofType:nil];
  NSString *images_misc_file = [[NSBundle mainBundle] pathForResource:@"images/misc/mainmenu_background.png" ofType:nil];
  </code></pre>
  
  <p>After this call, <code>images</code> contains the path <code>/Users/wic/Library/Application Support/iPhone Simulator/3.2/Applications/8F67150B-71E6-4735-8CC6-38B3CE6D3568/Foo.app/images</code>.</p>
  
  <p><strong>But <code>images_misc</code> and <code>images_misc_file</code> are <code>nil</code></strong>. Double-checking my file system to check if the file is there:</p>
  
  <pre><code>$ ls -l "/Users/wic/Library/Application Support/iPhone Simulator/3.2/Applications/8F67150B-71E6-4735-8CC6-38B3CE6D3568/Foo.app/images/misc/mainmenu_background.png"

  </code></pre>
  
  <p>Apparently the file is there.</p>
  
  <p>If I switch to "iPad Simulator 4.0", or any other simulator version for that matter everything works as expected.</p>
  
  <p>Is there something wrong with my setup, or is this correct behavior for <code>NSBundle</code> in iPad 3.2? I have no actual physical iPad to test it on unfortunately.</p>
