Message title translation

Translating "status" word into translation interface does not work for me.

Havin a look into better_message.module line 76 show me:

$output .= "<h2 class=\"messages-label $type\">" . t(drupal_ucfirst($type)) . "</h2>\n";

Replacing it by

$output .= "<h2 class=\"messages-label $type\">" . drupal_ucfirst(t($type)) . "</h2>\n";

seems to solve the problem.
