Support for multilanguage sites, Internationalization (I18N)

I need to display a menu with child pages of a defined parent. Unfortunately when I go with

PHP Code:

<?php get_i18n_navigation( 'defined-parrent-slug', 2,2, I18N_SHOW_PAGES ); ?>

then entries of that menu don't get a 'current' class when their corresponding pages are loaded.

I traced the issue to i18n_navigation/frontend.class.php, function getMenu(). There's this line:

PHP Code:

$currenturl = $breadcrumbs[ $icu ]; 


.
If I change it to

PHP Code:

$currenturl = return_page_slug(); 


everything seems to work correctly, breadcrumbs are working normally and menu entries get their 'current' class.

My question is what's the purpose of this line, why was it made like that and what are the consequences of my hack?
