First, please upgrade to 0.4.12 and see if that helps at all.  There
were some boto changes that may have affected you.

Second, if that fails, verify that duplicity backup files exist using
another S3 access tool, and post the first part of the listing.  Look
for oddities in the names that may have cause duplicity to miss match
the pattern its looking for.  S3 and boto are rapidly changing and a
previous reporter has seen the '+' sign dropped from a few of the files,
but not all of them.
