Temporary Solution to "Could not start kstartconfig. Check your installation"

Few weeks ago, I have installed KDE and after restarting and changing the session I get an error message "Could not start kstartconfig. Check your installation" and takes me back to the login screen. Back to the Gnome session, I have tried few from usual Gsearch but nothing worked. Here is a temporary solution.

• Create a new user (System->Administration->Users and Groups)

• Feel free to add user privileges according to your needs.

• Log out and login to KDE session with the new user name and password.

• Happy happy KDE.
