Can`t change default language for menus and windows

I have english and russian languages installed on my system and two user accounts. I want to change language (from russian to english), user specific settings (not system wide), for one of users.
I tryed to change language in user settings(clic on panel my name-button, then "users"), here in my account setting I change language from russian to english, but after logout/login and even restart nothing change. When I go to my account preferences again the russian language still selected.
Then I tried System Settings > Language Settings > Language. In the list of all the available interface languages I arranged languages as needed by dragging and dropping them. Then log out and back in and nothing happened again. If I go to System Settings > Language Settings > Language again the list of all the available interface languages is rearranged as were before changing(russian is still above others). When I start language-selector from terminal and do the same it say`s next:
 vasil@avma-desktop:~$ gnome-language-selector
