Presentation page link in menu

Hi there,

I am very satisfied with the Mantra theme but I have one problem that I hope is possible to solve:

I want to use a multi-language plug-in and the best one I can find is qTranslate. It works fine together with Mantra except from one thing. When one click the Home tab in the menu the selected language resets (I use a presentation page as Home).

According to the qTranslate FAQ this is a template problem. They suggest to change get_option(‘home’)  to bloginfo(). I can do that, but WHERE do I change this in Mantra?

Thank you!
