title: What is error code 35, returned by the telegram.org server
body: <p>My client often receives the following message container from the telegram server, seemingly at random:</p>
  
  <pre><code>{'MessageContainer': [{'msg': {u'bad_msg_notification': {u'bad_msg_seqno': 4, u'bad_msg_id': 6330589643093583872L, u'error_code': 35}}, 'seqno': 4, 'msg_id': 6330589645303624705L}, {'msg': {u'msgs_ack': {u'msg_ids': [6330589643093583872L]}}, 'seqno': 4, 'msg_id': 6330589645303639041L}]})
  </code></pre>
  
  <p>You may notice: <strong>'error code': 35</strong> above, but there is no description of what that error code means. So far I have been ignoring it but that is not a good long term solution IMHO. Any ideas what that error code means?</p>
