ffmpeg and se401 kensignton camera problem please help

[bacterium@xxxxxxx]

Hello.
I am having trouble recording with ffmpeg from my usb se401 camera. I 
get:
%ffmpeg -vd /dev/v4l/video1 file.mpeg
Output #0, mpeg, to 'file.mpeg':
  Stream #0.0: Video: mpeg1video, 160x128, 25.00 fps, 200 kb/s
  Stream #0.1: Adudio: mp2, 44100 Hz, mono, 64 kb/s
Audio sampling: 44100 Hz, mono
Video sampling: 160x128, RGB24 format, 25.00 fps
Press [q] to stop encoding
Segmentation fault

The light on the camera briefly goes on when I do this. It is always on 
while capturing. file.mpeg is empty.
It can see input from the camera in xawtv just fine and ffmpeg records 
from my tv tuner without problems.

Thanks
Adrian.
