Fatal error: Call to undefined function commerce_customer_access()

hey
getting an error at multiple places, after adding a new node type.
Fatal error: Call to undefined function commerce_customer_access() in /commerce/modules/customer/commerce_customer_ui.module on line 111

  foreach (commerce_customer_profile_types() as $type => $profile_type) {
    if (commerce_customer_access('create', $type)) {
      return TRUE;
    }
  }

which pretty much leaves the site unusable until i disable the module or comment out the function call.
