descriptions always shown

Description was always shown no matter what I choose in admin.
So found which line causes such a behavior.

file: taxonomy_vtn.pages.inc
line 374
function taxonomy_vtn_show_terms(...

function taxonomy_vtn_show_terms = TRUE --> always TRUE

quick fix
$show_voc_desc = variable_get('taxonomy_vtn_vocabularies_show_voc_desc', 1);
if (!is_object($params)) {
$params = new stdClass;
$params->check_omit = TRUE;
$params->title_mode = 'title';
$params->show_voc_desc = $show_voc_desc;
}
