Problem on user edition

If you have more than one scheme, on the user access page, default values of the second or third scheme are those of the first one.
Here is a bit of code that needs review to correct it :

on original :

           foreach ($vids as $vid) {
              $v = taxonomy_get_vocabulary($vid);
              $form['tac_lite'][$config['realm']][$vid] =
                _taxonomy_term_select($v->name,
                                      null, // name no longer used in new form api
                                      $account->tac_lite[$vid],

on modified :

            foreach ($vids as $vid) {
              $v = taxonomy_get_vocabulary($vid);
              $t=$config['realm'];
              $a=$account->$t;
              $form['tac_lite'][$config['realm']][$vid] =
                _taxonomy_term_select($v->name,
                                      null, // name no longer used in new form api
                                      $a[$vid],

Enclosed patch also.
