Some fixes have been pushed to gstreamer core and -base that are related 
to camerabin issues (yesterday and today). Can you give it a try with 
latest git gstreamer?

If it still doesn't work for you, can you provide a small sample 
application to reproduce the issue in a bug filled at 
https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer
