Hi

I'm a new user and try to use rdiff-backup in my environnement.
I got the foillowing problem with 1.05 and reproduce it with 1.1.14

The first rdiff backup is ok, but the following rdiff crash with traceback.

I made some tracking, but i'm new in python. This patch seems working, but i
don't know the reason of the 'assert'

                return Rdiff.get_signature(dest_rp)


My environnement :
fedora 7 lanch a rdiff on a nfs mounted directory (/net/d2r2/BACKUP/...)
The nfs has the particularity to force mapping of user :

/BACKUP    *(rw,all_squash,anonuid=99,anongid=99)
