Comment (by irl):

 I just went to try to reproduce this and I can't. ):

 I'm not actually able to make any download successfully over an ORPort
 though, I'm just getting this error over and over now:

 {{{
 >>> from stem import ORPort
 >>> from stem.descriptor.remote import get_consensus
 >>> tor26 = ORPort("86.59.21.38", 443)
 >>> get_consensus(endpoints=[tor26])

 >>> _.run()
 Traceback (most recent call last):

     raise stem.ProtocolError('Circuit response should be a series of RELAY

  response: %i' % len(reply))

 }}}

 This is a different issue, so feel free to close this ticket and make a
 new one if you wish.
