thanks for your diagnostic data.

yes, there is no problem in that run. 

in the meantime i've started up a blank unstable chroot, and i can
reproduce the issue on incremental backups.

exec summary: please ignore that error message.

i've checked the source, and this is actually working as designed:

upstream changed the handling of remote manifests in 0.7.14
to more-or-less blindly attempt to access an encrypted remote manifest
and if unsuccessful, log that as a nonfatal 'error'.

http://bazaar.launchpad.net/~duplicity-team/duplicity/0.8-series/revision/1252/duplicity/collections.py

as far as i can tell duplicity doesn't even attempt to fully interact
with gpg in this situation, and that's why you see the error message - which
is utterly benign: duplicity doesn't even NEED the remote manifest in
that situation (earlier on it's logged that "local and remote are in sync").

i'll raise a bug with upstream to improve the logging for this situation.

regards
az
