must be a bug in the cleaning code. Probably got introduced with the extra cleaning and keeping sigs for listing older backups.
in my case it keeps the files 'duplicity-full-signatures.*.sigtar.gpg' and 'duplicity-new-signatures.*.to.*.sigtar.gpg' .. seems to be all signatures to me (changed the subject accordingly)
i also see this behaviour with 0.6.08/11 and someone in the mailing list as well. see:
