Incompatibility with taxonomy.module

Please take a look at my issue in the taxonomy.module: http://drupal.org/node/1478944

After enabling metatag module, it was impossible to edit or delete taxonomy terms. I think, the problem is caused by the taxonomy.module - but I think, you should check your form fields as well to avoid problems.

I was able to save terms again after disabling the following lines in function metatag_metatags_form

<?php 
  $form += array('#submit' => array());
  array_unshift($form['#submit'], 'metatag_metatags_form_submit');
?>
