[Duplicity-talk] duplicity 0.4.3.RC12 failure on full backup

[Timothee Besset]

I am getting the following error on a Debian Etch GNU/Linux system when
doing the first backup:

# duplicity --full --cleanup --volsize 100 --short-filenames
--exclude-other-filesystems / file:///mnt/backup/duplicity
Warning, found incomplete backup sets, probably left from aborted session

In dmesg I see the following:

The system is on a software raid (raid1). I can't rule out that
something would be wrong with the raid setup, but the machine has been
running for months, and duplicity is the only software that triggers this.
