Contact reporting functions missing from mollom.pages.inc

Reporting a contact submission as inappropriate by pressing the link in the e-mail fails with the following error message:

warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'mollom_report_contact' was given in ...../includes/form.inc on line 371.

The item is declared at line 89 (code snippet below) of the file mollom.module. However the file mollom.pages.inc doesn't contain the function mollom_report_contact.

  $items['mollom/contact'] = array(
    'title' => 'Report',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('mollom_report_contact'),
    'access callback' => '_mollom_access',
    'file' => 'mollom.pages.inc',
    'type' => MENU_CALLBACK,
  );

I'am using mollom version 6.x.1.10 with Drupal 6.14.
