Can't get PB to work

I hope the answer would come in handy for other users, maybe it could become an episode for your screencast :)

I have a taxonomy browsing section with quite a simple 2-level URL scheme:

site.com/langcode/products/%manufacturer/
site.com/langcode/products/%manufacturer/%product

where manufacturer is a taxonomy term name (transliterated) and the product is a node title (transliterated). Both patterns are governed by Pathauto. So, for this path:
site.com/langcode/walt-disney/winnie-the-pooh
I should have breadcrumbs like:
[Home] > [Products] > [Walt Disney] > Winnie the Pooh

The product node "Winnie the Pooh" is an instance of a content type Product.
As much I could understand the PB philosophy, I created a definition like the one below, but could not get it to work when browsing through my products section. Any advice as per why, please?

How do I convert transliterated names from paths into human names needed for titles? (Currently I put identical values just to get anything).

$path_breadcrumb = new stdClass();
$path_breadcrumb->api_version = 1;
$path_breadcrumb->machine_name = 'producenci';
$path_breadcrumb->name = 'Producenci';
$path_breadcrumb->path = 'produkty/%manufacturer/%product';
$path_breadcrumb->data = array(
  'titles' => array(
    0 => '%manufacturer:name',
    1 => '%product:title',
  ),
  'paths' => array(
    0 => '%manufacturer:name',
    1 => '%product:title',
  ),
  'home' => 1,
  'translatable' => 1,
  'arguments' => array(
    'manufacturer' => array(
      'position' => 1,
      'argument' => 'term',
      'settings' => array(
        'identifier' => 'Taxonomy term: ID',
        'input_form' => 'term',
        'vids' => array(
          2 => '2',
          1 => 0,
        ),
        'breadcrumb' => 0,
        'transform' => 0,
      ),
    ),
    'product' => array(
      'position' => 2,
      'argument' => 'entity_id:node',
      'settings' => array(
        'identifier' => 'Node: ID',
      ),
    ),
  ),
  'access' => array(),
);
$path_breadcrumb->weight = 0;
