Just for completion, what exact GStreamer version are you running ? 
(gst-launch-1.0 --version)

The log does not say much, GST_DEBUG="v4l2*:7" would help. Currently the 
problem could be anything, but there is no obvious error. Also, can you 
check if you're pipeline is deadlocked. I notice in the trace the you 
are using libv4l2, for which we have found threading issue recently, and 
implemented a workaround (now in gst-plugins-good 1.4 stable).
