title: No Traceback From Django when DEBUG True
body: <p>I'm running under Fastcgi on Nginx. I have DEBUG = True, and I get the normal Django debug page when I go to an incorrect url on my site.</p>
  
  <p>However I have an Ajax call being made via jQuery and it returns "An unhandled exception was thrown by the application." instead of a Django traceback. I really can't figure out why. Any help would be appreciated.</p>
  
  <p>EDIT:</p>
  
  <pre><code>def FetchItem(request):
      mimetype = 'application/json'
      item_list = simplejson.loads(request.POST['item_list'])
      auth = functions.auth_session_check(request)
      if auth:
          response = [functions.item_by_id(itemid) for itemid in item_list]
      else:
          response = []
      return HttpResponse(simplejson.dumps(response), mimetype)
  </code></pre>
