KDE Unlock problem

Hi Guys,
I'm using KDE 4.4.5 on top of Ubuntu 10.04. Installed it from PPA repositories. Having problems unlocking locked session.
When using openGL screen savers, I can't even see unlock dialog box.
When using normal secreen savers like acquarium, I can see the unlock dialog box, but sometimes no matter how many times I try, I cannot unlock session it says "Unlocking failed". I have no choice than restarting my laptop and loosing all my work (Which makes me remember my bad days in windows!).
Pressing Ctrl+Alt+F2, logging in trough command line and running killall krunner_lock will not solve my problem. Becuase there is nothing named krunner_lock exist in my laptop!
qdbus org.kde.screenlocker /MainApplication quit DISPLAY=:0
qdbus org.kde.plasma-overlay /MainApplication quit DISPLAY=:0
will not solve the problem either. Because it says that it cannot connect to dbus server, even when run as root.
Any suggestion?
I can not let my computer go on and lock because then I'm not sure that I can unlock it after!

chown and chmode are not working either!

Here is result of the command which a group of people are glad to know that it solved their problem:

Source code

root@ario-laptop:/home/ario# chown root.root `which kcheckpass`
chown: missing operand after `root.root'
Try `chown --help' for more information.
root@ario-laptop:/home/ario# chmod 4755 `which kcheckpass`
chmod: missing operand after `4755'
Try `chmod --help' for more information.

For now decided to run this:

Source code

sudo chown root:root /usr/lib/kde4/libexec/kcheckpass
sudo chmod 4755 /usr/lib/kde4/libexec/kcheckpass

which I took from here.
Will come here and write if it changed any thing.
