.. as it fails for static OAI-PMH files (which we only need for dev/testing)

  After rollback it works for

   Live OAI-PMH feed (tested with Millersville's server)
   Static OAI-PMH file
   ftp harvest of .gz file (tested with New School's server)
   Static xml file from Seton Hall

  If there are other scenarios not tried here but for which it would
  fail, we would have to revisit of course.
