It appears really strange to me as well.. I've been testing cases similar to
yours for a while on embedded devices not seeing such a behaviour. Would it
be possible for you to check with valgrind?

Yes it definitely works, just grab an N900 ;) (to be honest, you need to
modify a couple of files to get it working with H263/G711 by default).

I should have a very simple test app somewhere working with gtk and on any
environments with a sane gstreamer installation and make it available if
needed, but you could just use the example pipelines reported in the rtpbin
documentation (just google "gstreamer rtpbin").
