Keyboard layout cannot be changed with keyboard shortcut when entering a password at unlock screen

[Oleg]

If my keyboard layout was different from English (Russian, for example), and the screen locks, then it stays in this nondefault layout and it may be changed to English only with mouse. That is very unconvinient.
This behaviour appeared only in Ubuntu 14.04
I use the default desktop manager (I believe it is Unity) and the default login manager (I believe it is LightDM).
It is not related only to my computer. A friend of mine also suffered from this new behaviour since 14.04, and that was one of the reasons why he switched to another distro.
