[Duplicity-talk] "Warning, found the following local orphaned signature files"

[edgar . soldin]

i keep on  getting this warning and can connect it to 
http://bazaar.launchpad.net/~duplicity-team/duplicity/0.6-series/view/head:/duplicity/collections.py#L150
where 'new-sig's are left in the local archive dir.

what is this about? why shouldn't they be deleted?
everything is fine when i delete them. i remove-older-than 3M and backup 
--full-if-older-than 1M.
