Comment:

 Have just run into this bug on another site I'm working on. I wanted to
 list all subcategories of a parent category, so used:

 `$terms = get_terms(array('child_of'=>1));`

 but was returned an empty array, because posts only exist in the
 subcategories, and none directly in the parent category.

 In this case, I could add the taxonomy parameter to fix it:

 `$terms = get_terms(array('child_of'=>1,'taxonomy'=>'category'))`

 But it would be nice if this bug can be resolved, given I reported it,
 along with a trivial one line fix, 3 years ago.
