title: Angular 2 ZoneAwareError in Tutorial, but only for chrome
body: <p>Hello here and thanks for helping ! 
  I'm performing the angular tutorial tour of heroes, and I have ended the point <a href="https://angular.io/docs/ts/latest/tutorial/toh-pt3.html" rel="nofollow noreferrer">4.Multiples Components</a>, but the content does not load (we see "Loading AppComponent content here ...") and I have this error on chrome developper tools: </p>
  
  <blockquote>
    <p>ZoneAwareError {__zone_symbol__error: Error: (SystemJS) Invalid or unexpected token
        SyntaxError: Invalid or unexpected token
            at eval…, __zone_symbol__stack: "(SystemJS) Invalid or unexpected token↵    SyntaxErro…n.js↵    Error loading </p>
  </blockquote>
  
  <p>I can't paste more because the error is displaying a very lot of information.
  The real problem is here: At this point of the tutorial, my app work perfectly on edge and firefox... I don't understand what is wrong with chrome :/ ...</p>
  
  <p>Thanks</p>
