- This bug is related to gstreamer video4linux2 plugin.
- This bug has been fixed with today (wed, 19 sep 2007) 
gstreamer-0.10-plugins-good update¹.

so, you can test webcam using:
$ gst-launch-0.10 -v --gst-debug=*v4l2*:5 v4l2src ! ffmpegcolorspace ! 
ximagesink

but, actually, I can't get it work in gstreamer apps, due to:
0:00:17.972419000  7422 0x82961a0 WARN               v4l2src 
gstv4l2src.c:1065:gst_v4l2src_get_mmap:<v4l2src3> warning: Got unexpected frame 
size of 8168 instead of 614400.
0

- This "warn" makes applications like gstreamer-properties or cheese
close unexpectly [test using: $ gstreamer-properties --gst-
debug=*v4l2*:5]


[just for information: these webcams are built-in in HP Pavilion series dv65xx]
