Can't see settings page

Clean install of the drupal 7.x dev version

enabling the module
navigating to admin/settings/admin_menu
brings me to this error and I don't see any of the settings

    *  Notice: Undefined index: admin_menu_theme_settings in drupal_retrieve_form() (line 436 of G:\xiosweb\testd7\includes\form.inc).
    * Warning: call_user_func_array(): First argument is expected to be a valid callback, 'admin_menu_theme_settings' was given in drupal_retrieve_form() (line 452 of G:\xiosweb\testd7\includes\form.inc).

can anybody else see this ?

testing this on Firefox Mozilla 3.0.13 (if it helps)
