get_posts by my custom term works correctly, but any additional category or post_type parameters seem to be ignored.
For example,
get_posts( array(
'my_taxonomy' => 'my_term_slug'
, 'category_name' => 'a_category_name'
));
retrieves posts in 'my term' regardless of category, and
get_posts( array(
'my_taxonomy' => 'my_term_slug'
, 'post_type' => 'post'
));
retrieves posts and pages in 'my term'.
Am I doing something wrong? Is it just not possible to combine custom taxonomy parameters with others in 2.9?
