You should not use category parameter to query custom taxonomy instead you should use tax_query parameter or directly custom taxonomy name as shown in the following query.
query_posts( array( 'post_type' => 'ublalfieportfolio', 'ublalfieportfolio-categories' => 'parketten', 'posts_per_page' => -1) );
Refer this page to know how to use custom taxonomy parameter in custom query.
