Webcam Live on (K)Ubuntu (breezy) (and kopete)

I just went trough the pain of getting my Creative Webcam Live working on Kubuntu. With the default installation, the system froze whenever any program (camorama, camstream) tried to use the webcam. The solution is here (thanks!).

Another program affected by this (now solved) problem is kopete, which failed upon trying to edit it settings, since the configuration dialogue access the webcam. Initially I thought this was a problem with kopete itself.
