yeah, please file a bug on launchpad, but check if there is a similar entry first please.
also point to this mail thread (via gmane or some) for others to read.
i still haven't and probably for some time will not have time to disect the issue.
first and foremost. the local cache (archive-dir) functionality was introduced with 0.6 by Kenneth (the maintainer), so we should ask him what he thinks the issue is here. i tried before, but haven't got an anser. i'll cc him again.
Ken: any idea on this? cite from below: "duplicity will sometimes decide to retrieve a manifest from the remote backup location even though there's a copy in the local cache"

Does duplicity like to retrieve the manifest from the remote if it's more than a week old?

I expected this to work since the local cache has everything duplicity needs, and in fact this worked with nightly backups for over two weeks. But now duplicity fails because it is trying to retrieve the last manifest, even though that file is in the cache.
