svn+ssh: Expected FS format '2'; found format '4'

Hello,

I tried to checkout from a server via svn+ssh:

rd_at_blackbox:~/Managed/Daten$ svn checkout
svn+ssh://rdorsch@hdcl037/var/svn/OSSM/svn-repository/trunk OSSM

Enter passphrase for key '/home/rd/.ssh/id_rsa':
rdorsch_at_hdcl037's password:
svn: Expected FS format '2'; found format '4'
rd_at_blackbox:~/Managed/Daten$

I think the problem is that on the server there is a default installation of
svn:

hdcl037: rdorsch $ svn --version
svn, version 1.4.2 (r22196)

  - handles 'file' scheme

hdcl037: rdorsch $

and a more recent version in a non-standard dir (which is added to my path
in .bash_profile)

hdcl037: rdorsch $ svn --version
svn, version 1.6.9 (r901367)

hdcl037: rdorsch $

I expect that .bash_profile is not executed when I do svn+ssh, but it is when
I do ssh into the host regularly.

I have now root access to the server containing the repository, I cannot use
keypair authentification.

Any suggestions are welcome.

Thanks,
Rainer
