Comment (by obache):

 questioned codes in `WP_Query::parse_tax_query()`.

 {{{#!php
                         if ( $t->query_var && ! empty( $q[ $t->query_var ]
 ) ) {
 }}}

 whereas `$t->query_var` is 'category_name', and `$q['category_name']` is
 0;

 should it be `strlen( $q[ $t->query_var ] ) > 0` instead of `! empty( $q[
 $t->query_var ] )` ?
