protocol is not supported

Hello, I am having one problem: I wanna use the left hand side (KDE-services) in my konquerer, but when I press the button for device or audiocd or network I get following message:                                  protocol is not supported                         devices (or audio or lan) This message occured first, after I upgraded to KDE3.3 What do I need to do to make this work again?? I am using Suse 9.0 KDE 3.3.1 (I just updated again via red-carpet) Thanks Thomas
