[live-usb-persistent] Changing language, folder Desktop is not traslated

Hello!

1) I have tested Edubuntu amd64 (53e0e2f038a8260c294e3a277881ad39 *raring-dvd-amd64.iso 20130128), on live usb persistent.
2) 1° boot: I have selected language "Inglish" and clicked "Try Ubuntu without installing".
3) 2° boot: I have selected language "Italian" and clicked "Try Ubuntu without installing". On the desktop, I have chosen that folders "Desktop" "Download" "Videos" etc., is traslated.
4) These folders is traslated, but the folder "Desktop" is not traslated in fact was created folder "Scrivania" in addition the folder "Desktop" (view screenshot attached).
