Your log seems to say that gstreamer is at 1.6.0, and therefore is coming
from some other layer than oe-core (which has 1.6.3). Disabling
introspection in recipes by using MACHINE_FEATURES_BACKFILL_CONSIDERED
only works if those recipes inherit gobject-introspection class, and so
this is what you should do. Or migrate from your custom gstreamer recipes
to ones provided by oe-core, and then you don't have to disable anything
at all most likely, and you will gain ability to use gstreamer from Python
scripts, Vala or other runtimes.
