 I think the {{{terms}}} property should also be set as an empty array, so
 I slightly modified the patch from [attachment:42327.patch] to:

 if ( 'count' == $args['fields'] ) {
         return 0;
 } else {
         $this->terms = array();
         return $this->terms;


 to avoid the mismatch between the {{{query()}}} method returning an empty
 array and the {{{terms}}} property being {{{null}}}, for the case when
 {{{fields}}} is not {{{count}}}. I think {{{terms}}} should be an empty
 array too in that case.

 [attachment:42327.2.diff] contains tests.
