Extra comma on Line 77 throws Fatal Error

Hi,

Just wanted to inform you that there's an errand comma on line 77 that throws a fatal error, both in your dev and stable version.

 drupal_set_message(
        t('Your version of <a href="@mimepart">!mimepart</a> is too old.  Please update to version 1.6.1 or later.',
          array(
            '@mimepart' => 'http://pear.php.net/package/Mail_Mime/docs/1.6.1/Mail_Mime/Mail_mimePart.html',
            '!mimepart' => 'Mail_mimePart',
          )
        ),
