[rdiff-backup-users] Problem with 0.12.2

[Alvin Gunkel]

Hello,

I've been using various versions of rdiff-backup for a while now and
periodically they would stop working, usually after I upgraded some suid
binary.  My fix until now has been to move the old backup directory aside
and start afresh.  However, when I try to do that now I get the following:

-su-2.05b$ /usr/local/bin/rdiff-backup -v 6 --exclude-device-files
--exclude-filelist /usr/home/backup/bin/excludes.dns address@hidden::/

(problem probably originated remotely)

My excludes.dns files looks like this (though I get the same error if I
leave off the excludes):

/proc
/tmp
/usr/local/bin/sudo
/usr/local/man
/usr/local/sbin/visudo
/usr/ports
/usr/share/man
/usr/X11R6/man
/var/msgs
/var/run
/var/spool
/var/tmp

On the server and several clients I am running rdiff-backup-0.12.2,
FreeBSD 4.7, librsync-0.9.5.1, and python 2.2.1.

Thanks for any insight you can give on this problem.
