KDE logout/shutdown dialog does not appear
 

Hello, I am using KDE (Debian 7) and the right click or the KMenu dialog for logout/shutdown/restart does not appear.
Also i have a startup script which doesn't load at all times. I have found sometimes the dialog appears for some sessions (randomly), and in those sessions the autostart apps actually work. So I guess they are somewhat related.
Please suggest me what steps should I take.

If you remove your startup script does everything go back to normal?

No, it doesn't.

So I guess that the script is not the problem. You could try to install or reinstall kde-full to make sure you didn't miss any kde packages. Are there any errors showing up in your log files? How did you install kde in the first place? Did you upgrade from squeeze to wheezy or is this your first installation?
