Poll shows even if question is empty

Polls were being displayed even when the poll question was blank.

Simple fix (sorry I don't know how to make a patch)

line 121:

replaced:
return theme('field', $node, $field, $items, $teaser, $page);
with
if ($items[0]['question'] == '') {
return '';
} else {
return theme('field', $node, $field, $items, $teaser, $page);
}
