Forum node breadcrumb not rendered when using url alias

My forum nodes are not getting the breadcrumb path rendered.

I 've noted on hansel_forum.module function hansel_forum_action_add_forum_path_get_crumbs() uses hansel_arg(0) to identify 'forum' and 'node', but in my case it is 'foros', as i' m using an path alias module.

May be the correct thing should be identify other way if current node is a forum or not, not just the URL ?

May be menu_get_object() ?
