Problem using http and https

Hi,
 
I can't seem to get http using apache mod_dav_svn to work.
Configured apache following the procedure indicated on the subversion book.
I created a repository using svnadmin (using fsfs).
Then imported an initial layout using svn and the file:/// type url. This
worked fine.
 
Then when I try to use http or https either via svn command line or firefox
browser, I get an error.
 
svn output:

[root_at_gate ~]# svn log https://localhost/svn/temp --username tbaptista
Authentication realm: <https://localhost:443> Subversion Repository
Password for 'tbaptista':
svn: PROPFIND request failed on '/svn/temp'
svn: PROPFIND of '/svn/temp': 500 Internal Server Error (https://localhost)

firefox browser output:

-
 <D:error>
<C:error/>
<m:human-readable errcode="13">
Could not open the requested SVN filesystem
</m:human-readable>
</D:error>

My configuration:
- Fedora Core 3 on i686
- subversion 1.1.1 from Fedora Core 3 updates
- Apache 2.0.52
- Apache subversion config:

<Location /svn>
  DAV svn
  SVNParentPath /home/svn
# SSLRequireSSL
  AuthType Basic
  AuthName "Subversion Repository"
  AuthUserFile /etc/svn-auth-file
  Require valid-user
</Location>

- the /home/svn and all repos subdirectories are owned by apache:apache and
are readable and writable by user and group.
 
That's it. Anyone know what I did worng?
