I have russian language installed as a second keyboard language.
Whenever I switch the language on hardware keyboard, message that the language was switched appears, but language still english. When I setup Russian as a first language- everything works fine, I can switch between Russian and English with almost no problems (English layout after switch is kind of messed up- some keys still play same function as on Russian)
Is there any way to fix it?

See ukeyboard, and bug 2501.
