menu_tree_all_data() returns incorrect "has_children"

Problem: menu_tree_all_data() is returning "has_children" => 1 (ie TRUE) for the first item in any branch that has NO children.

I will include my code below. The short of it:
1. get menu data with menu_tree_all_data()
2. run through it and generate HTML output

If you install the code below as a module, it will generate a block of your primary links menu. The debug code left on in that code will show the menu item titles and their has_children values. Look for a branch of your Primary Links menu where the first element has no children and has_children will still be 1 (true).

            case 'list':
                $block[0]['info'] = t('Custom Menu - Primary Links');
                break;
