title: Google App Engine: "Error: Server Error" but nothing in the logs
body: <p>I deployed an app to Google App Engine. When I navigate to it, I get this:</p>
  
  <blockquote>
    <p>Error: Server Error</p>
    
    <p>The server
    encountered an error and could not
    complete your request.</p>
    
    <p>If the problem persists, please report
    your problem and mention this error
    message and the query that caused it.</p>
  </blockquote>
  
  <p>All the pages do this. <code>appcfg.py upload_data</code> doesn't work either. I'm not sure why. Am I doing something wrong here?</p>
  
  <p>As an aside, it feels like sometimes I spend more time wrestling with GAE than I do actually writing code. (Although it's possible that my frustration is entirely my own fault.)</p>
