Password request not working when a machine resume from suspend?

[Hammer Attila]

Hy,

Some time I suspending my laptop when I goto a short time an another 
office, or lock the screen.
When my machine resume from suspend, not happening password request. Of 
course, importanter check boxes in GNOME Control Center/brightness and 
lock preference tool is checked.
After I archived my .gconf folder and .config/dconf/user file, I tryed 
remove my home folder the entire .gconf folder and .config/dconf/user 
file. Unfortunately nothing changed.
This is not a security bug? Already reported similar issue with Precise 
related?

Look following GSettings values, I generated a full list of settings 
with gsettings list-recursively command and search possible lock related 
settings:
org.gnome.desktop.screensaver lock-enabled true
org.gnome.desktop.screensaver logout-command ''
org.gnome.desktop.screensaver logout-delay uint32 7200
org.gnome.desktop.screensaver logout-enabled false
org.gnome.desktop.screensaver status-message-enabled true
org.gnome.desktop.screensaver ubuntu-lock-on-suspend true
org.gnome.desktop.screensaver user-switch-enabled true
org.gnome.desktop.lockdown disable-application-handlers false
org.gnome.desktop.lockdown disable-command-line false
org.gnome.desktop.lockdown disable-lock-screen false
org.gnome.desktop.lockdown disable-log-out false
org.gnome.desktop.lockdown disable-print-setup false
org.gnome.desktop.lockdown disable-printing false
org.gnome.desktop.lockdown disable-save-to-disk false
org.gnome.desktop.lockdown disable-user-switching false

I experienced first this issue under GNOME3 fallback session, but I 
tryed this problem with Unity 2d too.
Anybody have any ydea what setting key need setting to happening 
password request both resume from lock screen and resume from suspend 
operation?
