Comment (by drzraf):

 Adding that after installing the gstreamer0.10-x package
 I got this working:

 {{{
 gst-launch-0.10 -v v4l2src device=/dev/video0 \! xvimagesink
 }}}


 Comparing the GST_DEBUG='*:3' output with the one from pidgin I found one
 substantial difference:


 {{{
 v4l2src gstv4l2src.c:612:gst_v4l2src_get_caps:<v4l2src0>   # gst-launch
 v4l2src gstv4l2src.c:612:gst_v4l2src_get_caps:<vvconfig-videosrc>   #
 pidgin
 }}}


 And while the rest of this "probed caps:" lines is identical, the working
 gst-launch case results in:


 {{{
 v4l2src v4l2src_calls.c:278:gst_v4l2src_set_capture:<v4l2src0> Set
 framerate to 30/1 and duration to 0:00:00.033333333
 v4l2src v4l2src_calls.c:307:gst_v4l2src_capture_init:<v4l2src0> capturing
 buffers via mmap()
 /GstPipeline:pipeline0/GstV4l2Src:v4l2src0.GstPad:src: caps = video/x-raw-
 yuv, format=(fourcc)YUY2, width=(int)640, height=(int)480,
 interlaced=(boolean)false, pixel-aspect-ratio=(fraction)1/1,
 framerate=(fraction)30/1
 }}}


 meaning the format was successfully negotiated.
 This vvconfig-videosrc thing does not seems right, but don't know where it
 comes from (source code or config ?)
