KDE 4.4 logout problem

view full story

http://forums.opensuse.org – Hello. While I was using KDE 4.3.5 and previous all was OK. But after upgrading to KDE 4.4.0 or 4.4.1 I've got a problem. When I press any logout button (logout, reboot, shutdown, etc.) nothing happens. I only hear a logout sound. After that I can continue to work as usually, but clicking logout buttons doesn't cause logout menu. The only way to logout is to press "Ctrl+Alt+Backspace". :( This problem appears at both my computers, where I have openSUSE 11.2. Any ideas what to do? (Distributions)
