Revision graph fails with restricted domain auth

I am using TSVN with Collabnet Subversion Server (Apache) + mod_auth_sspi +
mod_authz_svn.

If my SVN user access configuration files reads

----------------------------------------------------
[/]
mydomain\mylogid = rw
----------------------------------------------------

Then I am able to checkout, commit and revision graph any file through TSVN.

However, if my config file reads

----------------------------------------------------
[rep:/mydirectory]
mydomain\mylogid = rw
----------------------------------------------------

I am able to checkout and commit files within
http://svnhost/svn/rep/mydirectory, but when I try to look at a revision
graph such a file, I get the popup

PROPFIND request failed on '/svn/rep'
PROPFIND of '/svn/rep': 403 Forbidden (http://svnhost)

and the graph window says "No graph available".

In the Apache access.log I see:

192.255.255.255 - mydomain\\mylogid [17/Sep/2007:15:14:43 -0400] "PROPFIND
/svn/rep HTTP/1.1" 403 320

So, in order to draw the revision graph for a URL to which I do have access
(e.g, http://svnhost/svn/rep/mydirectory/myfile.txt), the TSVN code
apparently does a PROPFIND on a URL to which I do not have access (i.e,
http://svnhost/svn/rep).

Although I am using mod_auth_sspi, I'm guessing that this problem is bad
juju between TortoiseSVN and mod_authz_svn, specifically, the TSVN revision
graph code is going where it oughtta not go for graphing information.

This same problem happens for me with TSVN versions both prior to and after
the recent revision graph rewrite, and so I'm guessing it has nothing to do
with that.

So, is this a TSVN bug? A feature? A stupid setting I missed? If there is no
easy setting to avoid this, can I play games in the SVN access file to grant
users access to the http://svnhost/svn/rep repository root directory without
granting them global repository access?
