[support] What's wrong with this query?

[Ms. Nancy Wichmann]

  $result = db_select('taxonomy_term_data', 't');
  $result->addField('t', 'tid');
  $result->condition('t.vid', $vids, 'IN')
    ->condition(db_or()->condition('t.description', "%$keys%", 'LIKE')->condition('t.name', "%$keys%", 'LIKE'))
    ;
  $result->execute();

  $found = NULL;
  foreach ($result as $row) {
    $output .= print_r($row, true);
  }
The Devel query log shows the query properly built. I copied the query from the log into PhpMyAdmin and it gets one row. But my code shows nothing fetched.
