kdetv crashes on startup

Binary package hint: kdetv

I've installed kdetv from the repository and every time I try to execute it crashes with the following output:

kdetv
kbuildsycoca running...
Reusing existing ksycoca
kdetv: simple.c:432: snd_mixer_selem_get_playback_switch: Asserzione '(elem)->type == SND_MIXER_ELEM_SIMPLE' fallita.
