screen don't lock when i press ctrl+alt+L on russian keyboard layout

[SerP]

screen don't lock when i press ctrl+alt+L on russian keyboard layout.

Somtimes, when i press ctrl+alt+L screen don't lock, keyboard layout applet show me "en", but if i press keys for change keyboard layout twice and then press ctrl+alt+L screen is locking.

I think hotkeys must work independently from keyboard layout.
