I try to get custom posts with predefined meta value.The query return nothing. 

```
    $args = array
    (
        'post_type' => 'item',
        'nopaging' => true,
        'tax_query' => array
        (   array
            (
            'taxonomy' => $taxonomy,
            'field' => 'term_taxonomy_id',
            'terms' => $term_id
            )
        ),
        'meta_query'  => array(
            array(         
                'key'     => 'from_import',  
                'value'   => '1', 
            )
        )
    );
    $posts = query_posts( $args );

```

When I remove meta\_query or tax\_query it works fine. How I can combine it?
