title: App Engine error log says "stacktrace () not available"
body: <p>In App Engine's log, I can see that sometimes there is an error.<br>
  Unfortunately there are no more details than the time, URL, parameters and this:</p>
  
  <pre><code>HttpMyReceiver: stacktrace () not available
  </code></pre>
  
  <p>How can I get more info about the error?</p>

  <p><i>More about my code, in case it helps: HttpMyReceiver is a class inheriting webapp.RequestHandler so it answers to HTTP requests. Its work is not that heavy in my opinion, no crazy loops as all of the heavy duty work is done by cron jobs. It should not be necessary, but in case you insist here is <a href="https://github.com/iniju/ankidroid-triage/blob/master/receive_ankicrashes.py#L465" rel="nofollow">the code</a>. In fact it is HttpCrashReceiver as its job is to receive crash reports from an Android app.</i></p>
