Hi.

This was a bug in the installer, and the solution has been found. Open Konqueror, and go to /home/<yourusername>/.kde/share/config/kdesurc. If you do not see the folder .kde, change the option in konqueror to show hidden files and folders. Once you have opened the text file, change:

super-user-command=sudo

to

super-user-command=su

I got the information from the following thread:

This should solve your problem.

Good luck,
