This looks like a bug indeed, I can't see anything wrong in your code.
The problem here most likely is that appsrc does not make sure that all
previous buffers are pushed downstream before using the new caps. Should
be relatively easy to fix by tracking caps together with buffers...

Could you file a bug about that with your sample code and what I said
above at http://bugzilla.gnome.org against GStreamer?
