Zend_Navigation: Breadcrumbs not rendered when i have request params

Question

i have setup Zend_Navigation and breadcrumbs seems to work only without query strings.

say i have setup my navigation like ...

...
array(
    'label' => 'Posts',
    'controller' => 'post',
    'pages' => array(
        array(
            'label' => 'view',
            'controller' => 'post',
            'action' => 'view',
            'route' => 'viewPostWithId',
            'params' => array('id' => null)
        )
    )
), ...

i even added in the route param. if i didnt have the params attribute, an error will be returned. if i went to /post/:id maps to /post/view/:id. currently, there is not error but the breadcrumbs are not rendered.
