title: Boto cannot iterate through instances
body: <p>The following code returns an empty list:</p>
  
  <pre><code>instancelist = list()
  instancelist = [x for x in conn.get_all_instances()]
  
  for instance in instancelist:
         print instance.groups
  </code></pre>
  
  <p>In every case the code never enters the for loop, could you please provide insight on why this is?  </p>
  
  <p>The boto API is supposed to return a list of all the reservation objects from conn.get_all_instances. 
  I am able to run/kill instances from the same connection object just fine.</p>
