Bug#265968: rdiff-backup: Can't restore incremental backups

["Kingsley G. Morse Jr." <change@nas.com>]

Package: rdiff-backup
Version: 0.13.4-3
Severity: critical
Tags: sid
Justification: causes serious data loss

Thanks for maintaining rdiff-backup. 

It's concept is great.

The main reason I'm writing is to report that, at
least on my box, rdiff-backup seems to be unable
to restore incremental backups. 

I suspect that I'm doing something wrong, but,
since no one knows if they can restore data until
they try and the consequences of failing can be
severe, I decided to email you.

For example, when I type:

    $ rdiff-backup --restore-as-of 3M /etc/passwd /tmp

it reports:

    Traceback (most recent call last):
      File "/usr/bin/rdiff-backup", line 23, in ?
        rdiff_backup.Main.Main(sys.argv[1:])
      File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 259, in Main
        take_action(rps)
      File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 239, in take_action
        elif action == "restore-as-of": Restore(rps[0], rps[1], 1)
      File "/usr/lib/python2.3/site-packages/rdiff_backup/Main.py", line 451, in Restore
        if not restore_root_set: assert restore_set_root(src_rp)
    AssertionError

However, incremental files exist:

    $ ls -l /mnt/backup/rdiff-backup-data/increments/etc/passwd*

reports:

    -rw-r--r--    1 root     root          259 Aug 16  2003 /mnt/backup/rdiff-backup-data/increments/etc/passwd-.2004-07-07T01:21:01-07:00.diff.gz
    -rw-r--r--    1 root     root          399 Aug 16  2003 /mnt/backup/rdiff-backup-data/increments/etc/passwd.2004-07-07T01:21:01-07:00.diff.gz

Thanks,
Kingsley
