Screensaver uses wrong keyboard layout

[Jean-Baptiste Lallement]

TEST CASE:
1. Add 2 keyboard layout: English and French in that order
2. Set a user password with characters that are placed differently on the keyboard in English and French like 'a', 'z', ... or digits
3. Logout/Login
4. Select French with the Keyboard indicator
5. Activate the screen saver (CTRL+ALT+L), then move the mouse or hit a key to wake it up.
6. Verify that the keyboard indicator of the screen saver shows 'FR'
7 Enter your password

EXPECTED RESULT:
Password is accepted

ACTUAL RESULT:
Password is rejected because it uses an english layout despite the indicator shows 'fr'
Switching the layout on the authentication dialog from fr to english then back doesn't have any effect.
