[rdiff-backup-users] problem restoring: Truncated header string (problem probably originated remotely)

[Jacques Botha]

Hi All

I'm having some troubles restoring to a machine across the network
Using rdiff-backup 0.13-4 on both the server and client
I have a a lot of successful backups of the machine:

rdiff-backup -l address@hidden::backup
address@hidden's password:
Warning: ownership cannot be changed on filesystem at backup/rdiff-backup-data

Don't assume that open-source software is inherently insecure because crackers 
can see the source code. History shows that crackers don't need source code 
to find exploits !
