In my case, the command proposed by Alkis Georgopoulos
gconftool-2 --type list --list-type string --set /desktop/gnome/peripherals/keyboard/kbd/layouts '[us,it]'
fixes the problem for the current session but the problem appears again after reboot.
I can also fix the problem for the current session deleting the USA layout in the keyboard preferences. Note that, in the keyboard preference the IT layout is correctly set, but not working unless I delete the USA layout.
