Several people have pointed out to me that there is a bug in get_enclosures 0.3 where you can get a divide by zero error on a download that happens fast enough that will come down in the same second. People are getting this running get_enclosures against my bittorrent RSS feed. I’ll release an update to this this evening, but the workaround is to not use the bittorrent feed with get_enclosures. It’s not going to do anything anyway, other than just getting down the metadata file. It doesn’t do the downloading of the actual thing behind the torrent, so it doesn’t do anything for you anyway.
