[ansel] SQL Query by DataTree_sql::_loadById(): SELECT datatree_id,
datatree_name, datatree_parents, datatree_order FROM horde_datatree WHERE
(datatree_id IN (2841) OR datatree_parents = ':2841') AND group_uid =
'horde.shares.ansel' ORDER BY datatree_id [on line 242 of
"/home/ben/pear/Horde/DataTree/sql.php"]

This definitely grabs the children of the gallery.  Horde might not use them,
but they are returned by the sql server. This is one of the 6 database calls
resulting from:

$galleries = $ansel_shares->listShares(Auth::getAuth(), $perm, false, $parent,
$allLevels);
