When I try to configure Kopete (Settings) it hangs. On the konsole appears:

libv4l2: error dequeuing buf: Erro de entrada/saída
VIDIOC_DQBUF error 5, Erro de entrada/saída
libv4l2: error dequeuing buf: Erro de entrada/saída
VIDIOC_DQBUF error 5, Erro de entrada/saída

It seams something related to webcam. But I don't have webcam. I have only a TV Card that uses "v4l". And I don't want to play it on Kopete!

What can I do to solve this problem?
