cannot get vote values through nodereference relationship

i have two content types. "application" and "reviews". reviews can be voted (with fivestar) and so do applications (multiple axis through fivestar). i want a block with the list of review and the overall rating of the __application__ aside. so i added a relationship for the node-referred content (call this: relative application) and another relationship "vote results" that uses the latter.

it seems that this doesn't work as the join of votingapi_cache results are made with the node table (read: review table) instead of the content_type_application. My view follows:

$view = new view;
$view->name = 'prova';
$view->description = 'prova';
$view->tag = 'block, home';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('relationships', array(
  'field_application_ref_nid' => array(
    'label' => 'Relative application',
    'required' => 1,
    'delta' => -1,
    'id' => 'field_application_ref_nid',
    'table' => 'node_data_field_application_ref',

));
$handler = $view->new_display('block', 'Block', 'block_1');
$handler->override_option('block_description', '');
$handler->override_option('block_caching', -1);

and this is the erroneous generated query:

SELECT node.nid AS nid,
   node.title AS node_title,
   votingapi_cache_node_percent_overall_average.value AS votingapi_cache_node_percent_overall_average_value
 FROM node node 
 LEFT JOIN content_type_review node_data_field_application_ref ON node.vid = node_data_field_application_ref.vid
 INNER JOIN node node_node_data_field_application_ref ON node_data_field_application_ref.field_application_ref_nid = node_node_data_field_application_ref.nid
 LEFT JOIN votingapi_cache votingapi_cache_node_percent_overall_average ON node.nid = votingapi_cache_node_percent_overall_average.content_id AND (votingapi_cache_node_percent_overall_average.content_type = 'node' AND votingapi_cache_node_percent_overall_average.value_type = 'percent' AND votingapi_cache_node_percent_overall_average.tag = 'overall' AND votingapi_cache_node_percent_overall_average.function = 'average')
 WHERE node.type in ('review')

afaik it should be (note that the aliased table differs)

 LEFT JOIN votingapi_cache votingapi_cache_node_percent_overall_average ON node_node_data_field_application_ref.nid = ...

to get the application votes.
