Comment (by garrett-eclipse):

 My bad sorry @betimademi I read that as custom code. I see now that
 @jorbin pointed it out that it's part of core. Please retract my previous
 point to support. Seems like in this case the $old_value just needs to
 undergo the is_array check before using count here;
