title: Sencha touch application loader keeps blinking
body: <p>I just setup an all basic sencha touch application. Just did <code>sencha generate app *Name* *Directory*</code>. The app is generated without any error, but when I start the server and load the application in Chrome (just updated to the latest version), I get a blue screen with three blinking dots.</p>
  
  <p>In the JS console, there is this:</p>
  
  <blockquote>
    <p>Uncaught TypeError: Object [object Object] has no method 'append'", occured in sencha-touch.js</p>
  </blockquote>
  
  <p>Is this a common issue? Did I do anything wrong? The app is generated with sencha touch 2.2.1 and ruby 1.9.3. </p>
