[rdiff-backup-users] Can't even test server mode

[Dr Aldo Medina]

I'm trying to backup my server (linuxserver). It runs in Debian Woody
with rdiff-backup-0.6.0-1 package. My backup machine (linuxclient) runs
Debian Sarge with rdiff-backup-0.10.1-3. However, if I try to run
--test-server, I get this message from my sarge machine:

rdiff-backup --test-server linuxserver::/test

Traceback (most recent call last):
  File "/usr/bin/rdiff-backup", line 5099, in ?
    Globals.Main.Main()

    if format_string == "o": result = cPickle.loads(self._read(length))
ImportError: No module named rdiff_backup.connection
Fatal Error: Truncated header string (problem probably originated
remotely)

Couldn't start up the remote connection by executing

    ssh -C linuxserver rdiff-backup --server

Remember that, under the default settings, rdiff-backup must be
installed in the PATH on the remote system.  See the man page for more
information.

And if I try the same from the server to backup:

rdiff-backup --test-server linuxclient::/test

Any ideas? TIA.
