Package: rdiff-backup
Version: 1.2.8-6
Severity: important

I have two newly created Squeeze 6.0.6 installations from which I am attempting to perform daily backups.  Both systems have the same package versions as shown below.  The first system has been performing regular backups for the past month, however the second system, built last week, is issuing the error shown in the traceback below.  I have thus far not been able to create the initial backup on this new system.

The command issued on both servers to perform a backup:
# rdiff-backup --exclude-device-files --exclude-fifos --exclude-sockets --exclude '/core' --exclude '/lost+found' --exclude '/tmp/*' --exclude '/var/lib/nfs/rpc_pipefs/*' --exclude '/var/log/*' --include '/var' --exclude-other-filesystems / <backup-server-name>::/Backup/$HOSTNAME
