Problem with loading camera on KDE 3.5 RC1

I recently upgraded to KDE 3.5 RC1 and when I plugged in my camera and was asked to open it, I said OK but got the following error: Could not start process Unable to create io-slave: klauncher said: Unknown protocol 'camera'. Does anybody know what I can do? I had no problem before I upgraded to KDE 3.43 but then my upgrade was not smooth. I by mistake used the yast -i *.rpm command, instead of using the YaST GUI to upgrade the KDE packages I had installed, so I went back to YaST GUI and removed the KDE packages which I don't use. Maybe that created some problem? Thanks in advance for any help, Shriramana.
