Cart shortcode doesn't show anything

I have the same problem. After reviewing the plugin code I found that the cart shortcode handler definitely won’t show anything if the cart is empty (this is from version Version 4.1.7):

function show_wp_shopping_cart_handler($atts) {
    $output = "";
    if (cart_not_empty()) {
        $output = print_wp_shopping_cart($atts);
    }
    return $output;
}

I ended up adding an “else” clause to that handler just to make sure the shortcode is being called (and it is).

This seems to be a weak point in this handler. Shouldn’t it show something regardless?
