Comment 3 for bug 519948

I experience this defect as well.

I found the --extra-clean parameter from the discussion at http://lists.gnu.org/archive/html/duplicity-talk/2010-02/msg00012.html but that doesn't seem to do anything when supplied as a parameter to remove-all-but-n-full, and removes current signature files (or seems like it would, I didn't use --force) when supplied to cleanup.
