title: require.js modules not loading properly
body: <p>I have my bootstrap file which defines the require.js paths, and loads the app and config modules.</p>
  
  <pre><code>// Filename: bootstrap
  
  // Require.js allows us to configure shortcut alias
  // There usage will become more apparent futher along in the tutorial.
  require.config({
      paths: {
          bfwd: 'com/bfwd',
          plugins: 'jquery/plugins',
          ui: 'jquery/ui',
          jquery: 'jquery/jquery.min',
          'jquery-ui': 'jquery/jquery-ui.min',
          backbone: 'core/backbone.min',
          underscore: 'core/underscore.min'
      }
  });
  console.log('loading bootstrap');
  require([
      // Load our app module and pass it to our definition function
      'app',
      'config'
  ], function(App){
      // The "app" dependency is passed in as "App"
      // Again, the other dependencies passed in are not "AMD" therefore don't pass a parameter to this function
      console.log('initializing app');
      App.initialize();
  });
  </code></pre>
  
  <p>app.js is loaded like it should, and it's dependencies are loaded. it's define callback is called, with all the correct dependencies passed as arguments. No error is thrown. HOWEVER, in the bootstrap's callback, App is undefined! no arguments are passed. What can be causing this? Here's my app file ( modified for space)</p>
  
  <pre><code>// Filename: app.js
  define(
      'app',
      [
          'jquery',
          'underscore',
          'backbone',
          'jquery-ui',
          'bfwd/core',
          'plugins/jquery.VistaProgressBar-0.6'
      ], 
      function($, _, Backbone){
          var initialize = function()
          {
              //initialize code here
          }
          return 
          {
              initialize: initialize
          };
      }
  );
  </code></pre>
