Looks like some kind of Gstreamer issue.

You could also try:
gst-launch -v v4l2src ! fbdevsink

or gst-launch -v v4l2src ! filesink location= raw.data

If you still get Gstreamer issues you can try v4l2grab utility:
http://git.linuxtv.org/v4l-utils.git/blob/de42be924c5154732bc8dfd1c8bc7812985ab2d6?f=contrib/test/v4l2grab.c

Good luck!
