The webcam works with LUVCview (Version 20060207, LUVCview download) in all resolutions. But wenn i start kopete and go to the webcam dialogue, i see only [QT] and in the same time i get following errors in the terminal:

QPixmap::convertFromImage: Cannot convert a null image

Then, when i change the device to my tvcard output /dev/video0 and back to the webcam (USB Video Class device on /dev/video1) kopete crashes.

well, here it 'just works'. i guess you had a look at the settings in kopete (tough not much to setup there). i tested it first with kdetv (yeah can see webcam as well). maybe it can help you?

kopete + webcam is pretty new (and will get a serious rework for KDE 4) so it's possible you won't be able to fix it easilly, sorry.
