Getting strange '501 Not Implemented' errors... ?

Hello,

I am running into a strange problem that I can't seem to find much
help for on the web. Sometimes (but not always) I am getting the
following error trying to access a subversion repository over http
from a remote host.

transposon:~$ svn ls http://centromere.statgen.ncsu.edu/svn/Project/
--username guest
svn: PROPFIND request failed on '/svn/Project'
svn: PROPFIND of '/svn/Project': 501 Not Implemented
(http://centromere.statgen.ncsu.edu)

Other times it works fine:

transposon:~$ svn ls http://centromere.statgen.ncsu.edu/svn/Project/
--username guest
Authentication realm: <http://centromere.statgen.ncsu.edu:80>
Subversion Repository
Password for 'guest':

I moved this repository from my home directory to /var/svn and did
chown -R www-data.www-data to make it accessible to apache.

Here is my configuration:

<Location /svn>

   # Uncomment this to enable the repository,
     DAV svn

   # SVNPath /home/bredelings/SVN/Project/
     SVNParentPath /var/svn

     AuthType Basic
     AuthName "Subversion Repository"
     AuthUserFile /etc/apache2/dav_svn.passwd

     Require valid-user

   # Uncomment the following line to enable Authz Authentication
     AuthzSVNAccessFile /etc/apache2/dav_svn.authz
</Location>

WWW Browsing of the repository always works. After web browsing, then
for a little while following, I can access it from the command line.

I am using apache2 2.2.3 and subversion/libapache2-svn 1.4.2 from
Debian. System is linux 2.6.16...

Also, I have also noticed that if I mis-spell the URL, then I get the
same error (note the "d" in "svnd" in the second try.)

transposon:~$ svn ls http://centromere.statgen.ncsu.edu/svn/Project/
--username guest
svn: PROPFIND request failed on '/svn/Project'
svn: PROPFIND of '/svn/Project': 501 Not Implemented
(http://centromere.statgen.ncsu.edu)
transposon:~$ svn ls http://centromere.statgen.ncsu.edu/svnd/Project/
--username guest
svn: PROPFIND request failed on '/svnd/Project'
svn: PROPFIND of '/svnd/Project': 501 Not Implemented
(http://centromere.statgen.ncsu.edu)

But if I view the URL with Firefox, then it works correctly again:
transposon:~$ svn ls http://centromere.statgen.ncsu.edu/svn/Project/
--username guest

Any ideas?
