0.6.18 was a buggy release. It is possible that it produced a backup that was incomplete. This looks like the case in your report above. I don't have it in front of me, but there is a method to manually restore files as long as the difftar files are complete. Look for answers by edso (Edgar Soldin) in the duplicity-talk archives.
