The whole topic is year old, and there are few good solutions posted on this thread at Qian Qin’s Support forum.

I posted this one, which is altered Woo Themes workaround for the same problem with Home link, modified using qTranslate getLanguage() function.

This is a template. Make a page called anyhow on this custom template basis, than link to it in WP menu. Use URL you need in template, it will redirect language accordingly.
Now you can link to your Home page from WP Menu and it will be correctly translated.
