To reproduce this issue just do the following:

% wget http://torrents.linuxmint.com/torrents/linuxmint-12-gnome-cd-nocodecs-64bit.iso.torrent
% rtorrent linuxmint-12-gnome-cd-nocodecs-64bit.iso.torrent
(Wait until the torrent finishes)
% sudo echo 3 > /proc/sys/vm/drop_caches
(Rehash the torrent (Ctrl-R))
The torrent doesn't rehash successfully and a few hunks are
missing/corrupted and need to be downloaded again.
