Can't set position pointer

hi, all,

I just setup a subversion1.3.0 on Redhat9.0, with apache2.2.0. and my httpd.conf content:
<Location /svn>
          DAV svn
          SVNListParentPath on
          SVNParentPath /home/svnadm
          #AuthzSVNAccessFile /home/svnadm/etc/svn-access-file
          Require valid-user
          AuthType Basic
          AuthName "asc first repository"
          AuthUserFile /home/svnadm/etc/passwdfile
          SVNAutoversioning on
</Location>
        I use "svn import"£¬or TortoiseSVN to import£¬user name and password all are right.but the system answer me£º
svn: PROPFIND request failed on '/svn/repos'
svn: Can't set position pointer in file '/home/svnadm/repos/db/revs/0': Invalid argument

repos is created by user svnadm with command "svnadmin create". what's going on?
