Returns the number of elements in array_or_countable. When the parameter is neither an array nor an object with implemented Countable interface, 1 will be returned. There is one exception, if array_or_countable is NULL, 0 will be returned.
If the item is null, it should indeed return 0.

So we have to do extra checks ... and re-write all the existing code ...
echo count($item);
used to simply return '0' or the number of items and the templates use
that simple form where one displays the totals ...
