bad translation on itunes user interface

There is an error in the translation of the software Itunes 11 from english to spanish. When any idevice is connected to the computer, the "free" space storage is translated as "gratis" (in spanish). The correct word is: Libre not "gratis".

I have checked another way to post this error but apple does not support e-mail or chat contact for itunes so i did it from here.

Please fix this. Is very annoying.

Thank you in advance.

Dani.
