Bug#446906: gnome-screensaver does not grab keyboard input

Package: gnome-screensaver
Version: 2.18.2-1
Severity: important

When I lock screen the password input box is immediately displayed, but
there is no cursor in the text input field. Writing anything on keyboard
produces no change. 
I tried this: 
- opened konsole
- locked screen (using shortcut ctrl+alt+ins I configured before)
- instead of blanking screen and display the password input box only on
  keyboard/mouse event, gnome-screensaver displayed the input box
  immediately. In the text input field there was no cursor (neither
  blinking nor static, none at all)
- I WROTE SOMETHING ON THE KEYBOARD, nothing happened apparently (static
  image with the password input box on the screen, mouse arrow working
  as it might) - this is important
- I waited 30s, the input box disappeared and reappeared immediately,
  this time the cursor was present and blinking
- I entered my password and hit enter, the screen unlocked
- surprise! What I wrote on the keyboard before the input box flashed
  ant the cursor reappeared was there on konsole. 

During the first 30s: 
- the keyboard input is not grabbed by gnome-screensaver but from the 
  application which had focus when the screen was locked
- the mouse input is grabbed correctly, but clicking on any button on
  the box does nothing, except showing the button-pression animation

Independently from the actions taken, after 30s the situation recovers
automatically and the input box works again, allowing password typing
and screen unlocking.
