 By default, the 'category_children' option is populated with a serialized
 empty PHP array. So upon first call, it correctly yields an *empty* array.
 This code succeeds in the if() block and returns the empty array to the
 calling function.

 My suggestion is to change this to something like: if (!empty($children))
