Retrieval of mergeinfo unsupported (even after repo upgrade)

Hi,

I've recently updated my Subversion package on Debian Etch to 1.5.1 via
a back-port. I've gone through what I believe are all the appropriate
steps but cannot for the life of me get past the following error message
when I try to run svn mergeinfo:

     Retrieval of mergeinfo unsupported by '.'

The '.' isn't important as I get the same message whether I'm SSH'd on
to the server or using TortoiseSVN through Windows.

I'll take you through what I did to upgrade and test step by step:

Update of Subversion

Added the following line to /etc/apt/sources.list:

     deb http://www.backports.org/debian etch-backports main contrib
non-free

and then ran

     apt-get -s -t etch-backports install subversion

Checked the version of the subversion installation

Done this by running

     svnadmin --version

and got the following output:

     svnadmin, version 1.5.1 (r32289)
     compiled Dec 11 2008, 18:10:14

Checked the client too using

     svn --version

and got the following

     svn, version 1.5.1 (r32289)
     compiled Dec 11 2008, 18:10:14

Ok, so all looking good so far.

Now I just need to upgrade the repository. After plenty of research, the
most foolproof way to do this seemed to be to dump the repository and
then load it again. So here's what I did:

     svnadmin dump /var/svn/repo > repo.dump
     rm -aR /var/svn/repo/*
     svnadmin create /var/svn/repo
     svnadmin load < repo.dump

All that seemed to work fine. I then checked to see if the repository
had been upgraded by looking at the contents of /var/svn/repo/db/format
which gave:

     3
     layout sharded 1000

Again this indicated a Subversion 1.5 repository so all looking good.

Now I try and do a merge using the Subversion client in Debian:

     svn mergeinfo https://mysvn/repo .

and I get the following error:

     svn: Retrieval of mergeinfo unsupported by '.'

I get the same error message whether I'm using the Debian shell on the
same server or if I'm connecting via TortoiseSVN and a Windows box.

If I browse to the repository using my web browser, the version number
at the bottom reads:

     Powered by Subversion version 1.4.2 (r22196).

In case it helps, the created date on mod_dav_svn.so is 2009-08-06 18:29

I just cannot figure out why I'm getting this message so any help
pointing me in the right direction would be greatly appreciated. All the
forum and mailing list posts that I found relating to this error were
solved by doing an svnadmin upgrade, though I have actually tried that
and still no joy.

Thanks in advance,

James.

PS. I have already posted this to serverfault.com but not much joy so far.
