This doesn't make any sense. Everything seems correct. :-(

You could try deleting all of the *.pyc files in /var/lib/python-support/python2.4/rdiff_backup/ ... those files are just temporary compiled Python and could potentially cause problem if they are out of sync. Python will regenerate them automatically from the source.

Doesn't help :-(

Also, what version of Python is running on the server? (pc00136)

address@hidden:~ #
  python -V
Python 2.4.4
address@hidden:~ #
  dpkg -l python
ii  python                               2.4.4-2                              
An interactive high-level object-oriented language (default version)

And did you do the --restrict-read-only options that Dean suggests in his HOWTO?

Yes, .ssh/authorized_keys contains

command="rdiff-backup --server --restrict-read-only 
/",from="gatefmtc-new",no-port-forwarding,no-X11-forwarding,no-pty ssh-rsa ....

I guess I will have to setup Debian to check this. I just tried pushing a restore with 1.1.15 with Centos client and Ubuntu server with no trouble.

I had a quick look at 
<http://backports.org/debian/pool/main/r/rdiff-backup/rdiff-backup_1.1.15-2~bpo40+1.diff.gz>,
 and it doesn't seem to alter any code, which makes it more plausible to me it is 
either a nasty config error on my side (or some issue in the dependencies?)

sh-3.1$ apt-cache show rdiff-backup | grep Depends
Depends: libc6 (>= 2.3.5-1), librsync1 (>= 0.9.6), python (<< 2.5), python-support 
(>= 0.3.4), python (>= 2.4)


Thx for looking into this!
