Sorry, it appears that I spoke too soon. It works for backups to a remote 
machine, but local ones still fail, with the following trace:

Previous backup seems to have failed, regressing destination now.

This presumably means that this box isn't being backed up (locally) right 
now, which is worrying. Any ETA on a fix, before I have to downgrade all 
my boxen to 0.12.8 to get my backups working again?

rdiff-backup was run with the following command line:

        rdiff-backup --force --exclude-device-files \
        --exclude /dev/log \
        --exclude /dev/reboot \
        ... more excludes ... \
        --exclude /var/state \
        / /mnt/backup/server/rdiff

rdiff-backup version 1.0.0 on Fedora Core 1, python 2.2.3.

Cheers, Chris.
