mod_dav_svn assert on root location

[Erez Zarum]

I am trying to create a master slave configuration with proxy requests
through the slave, i have used this configuration on the slave:
        <Location />
                DAV                     svn
                SVNPath                 /scratch/repo
                ....
                SVNMasterURI            "http://master.server.com/svn";
                ...
        </Location>

In 1.7.7 the SVNMasterURI won't let me use http://master.server.com/
in 1.6.19 it will.
But when i use <Location /> i get the following assert in the apache
error_log (the main log): "httpd: subversion/mod_dav_svn/mirror.c:47:
proxy_request_fixup: Assertion `(uri_segment[0] == '\0') ||
(uri_segment[0] == '/')' failed."
If i use <Location /url> then everything works as expected.

Thanks,
 Erez
