14399	get_term_children doesn't call clean_term_cache() if necessary	miradev		"1. Create a taxonomy on something 'non standard'[[BR]]

2. Create a (parent) term.[[BR]]

3. Create a child term. [[BR]]

4. Retrieve child terms of the parent term using, amongst others, get_term_children().

Roughly:

{{{
register_taxonomy( 'where-you-live', 'user', array('hierarchical' => true,  'show_ui' => true, 'query_var' => true, 'label' => __('Where they live')) );

$country = 'USA';
$state   = 'New York';

$tax_country = wp_insert_term($country,  'where-you-live');
$country_term_id = $tax_country['term_id'];
wp_insert_term($state, 'where-you-live', array('parent'=>$country_term_id));

$state_terms = get_child_terms($country_term_id, 'where-you-live');
error_log(print_r($state_terms,1));
}}}

I am expecting an array containing the 'New York' child term, but I get nothing.[[BR]]
Have also tried get_terms() with child_of or parent args, which also fail (presumably for the same reason?)."	defect (bug)	reopened	normal	Future Release	Taxonomy	3.0	normal		needs-patch
