Using Kerberos-Authentication with subversion 1.4.2

Hi,

I'm trying to use kerberos-authentication for my subversion repositories but
the clients in version 1.4.2 fail to connect with HTTP-Error 207
Multi-Status. Older 1.3.2 clients and browsers are able to connect to the
server.
The server uses subversion-1.4.2, apache-2.2.3 and
lib-apache-mod-auth-kerb-5.3

My apache configuration for the svn location looks like this:

  <Location /svn>
    DAV svn
    SVNParentPath /var/lib/svn

    AuthType Kerberos
    AuthName "Kerberos Login"
    KrbMethodNegotiate on
    KrbMethodK5Passwd on
    KrbAuthoritative on
    KrbAuthRealms UNI-PADERBORN.DE
    KrbServiceName HTTP
    KrbVerifyKDC on
    Krb5Keytab /etc/keytab.svn
    AuthGroupFile /etc/apache2/htgroup
    require group staff
  </Location>

This smells like a bug either in my configuration or svn-1.4.2.
