title: pydev on aptana3 unable to import gi.repository
body: <p>the following code should work</p>
  
  <pre><code>import gi
  import gi.repository
  </code></pre>
  
  <p>this works in a python shell. And it also works if I save the file as a script then launch it  in a terminal.
  but in aptana3 i get this:</p>
  
  <pre><code>import gi.repository
  ImportError: No module named repository
  </code></pre>
  
  <p>i think this <a href="http://sourceforge.net/tracker/index.php?func=detail&amp;aid=3284889&amp;group_id=85796&amp;atid=577329" rel="nofollow">bug report</a> may have a clue</p>
