Using sulu's xkb, You don't need to use english only, neither in Maemo settings, or in LXDE (writing just in case).

If sulu doesn't use extkbd, I bet my left shoe, that it is related. Not quite a bug - on itself, it doesn't break anything - but, need to be considered, while using Maemo xkb (folder) for any "external" purpose.
