In libsvn_ra/ra-loader.c:svn_ra_get_location_segments the failure of the
get-location-segments REPORT is expected to generate
SVN_ERR_RA_NOT_IMPLEMENTED:

  if (err && (err->apr_err == SVN_ERR_RA_NOT_IMPLEMENTED))
    {
      svn_error_clear(err);

      /* Do it the slow way, using get-logs, for older servers. */
      err = svn_ra__location_segments_from_log(session, path,
                                               peg_revision, start_rev,
                                               end_rev, receiver,
                                               receiver_baton, pool);
    }

but libsvn_ra_serf is returning SVN_ERR_RA_DAV_REQUEST_FAILED

(gdb) p err[0]
$3 = {apr_err = 175002, message = 0x7ffff6f85e7d "traced call", 
  child = 0x7ffff7f300a0, pool = 0x7ffff7f30028, 
  file = 0x7ffff5a4ab60 "../src/subversion/libsvn_ra_serf/getlocationsegments.c", line = 205}
(gdb) p err[0].child[0]
$4 = {apr_err = 175002, 
  message = 0x7ffff7f300f0 "Unexpected HTTP status 501 'Method Not Implemented' on '/obj/repo/!svn/bc/1/A'\n",
child = 0x7ffff7f30140, pool = 0x7ffff7f30028, 
  file = 0x7ffff5a4edf0 "../src/subversion/libsvn_ra_serf/util.c", line = 2440}
