No menu callback implemented for deny access oauth/authorization/deny/

In oauth_common.pages.inc, the function _oauth_common_authorize() returns a form with two links to deny access to an application which requested authentication via oauth.

    $form['warning'] = array(
      '#type' => 'item',
      '#value' => l(t('If you don\'t know what !appname is, or don\'t want to give it access to your content, just click here and we\'ll take you away from this page without granting !appname any access to !sitename.', $msgargs), 'oauth/authorization/deny/' . $token->key),
      '#attributes' => array(
        'class' => 'abort-authorization',
      ),
    );

and

    $form['deny'] = array(
      '#type'   => 'item',
      '#value'  => l(t('Deny access'), 'oauth/authorization/deny/' . $token->key),
      '#attributes' => array(
        'class' => 'deny-access',
      ),
    );

The menu callback has not been implemented in oauth_common_menu(). Perhaps it has been implemented somewhere else, so forgive my ignorance.

I thought to post this bug already, before trying to solve it.
