Icon path and lang prefixe

Hello

Very nice module.
I have a little problem when I try to put an icon on a link.

The path of my icon look like this : /mySite/sites/all/themes/myTheme/css/images/home.png

But when I try to view the menu, the icon is not displayed because due to the lang prefix, this path is called : /mySite/fr/sites/all/themes/myTheme/css/images/home.png

How to do to get the good path without prefix ?

Thanks in advance
