WPML language switcher URL issue on home page

Please fix the code for future realeases in wp-content/themes/enfold/config-wpml/config.php in line 488 from:
if(is_home() || is_front_page()) $url = $sitepress->language_url($lang['language_code']);
to:
if(is_home() || is_front_page()) $url = $sitepress->language_url($lang);

To avoid home page language switch to result in 404 page, I had to change this line. Will it cause any theme related issues by doing this?

Please see this thread – WPML support
