auxpropfunc error no mechanism available

[Jacob McCoy Wade]

I think since updating my subversion package to 1.6.9, I am seeing this
repeated twice in my logs every 60 seconds:
org.tigris.subversion.svnserve[47023]: launchproxy[47023]:
/opt/subversion/bin/svnserve: Connection from: 127.0.0.1 on port: 51712
svnserve[47024]: auxpropfunc error no mechanism available

Nothing seems wrong with my repository, but I just can't figure out the
auxpropfunc error as I am not using sasl authentication, just a plain
old passwd file.

Here is my svnserve.conf file

[general]
anon-access = none
auth-access = write
password-db = passwd
realm = svn

and here is my plist file (this is running on an xserve running 10.6.2)
