Whoops... my mistake.

Hrm... that is problematic...

There are a variety of methods in the GStreamer APIs which takes GTypes as
part of their function definition.  For example:

GstPluginFeature *
gst_plugin_find_feature(GstPlugin *plugin, gchar *name, GType type)

And there are others.  For example, there are a couple of factories which
take GType instances as part of their constructor.  There aren't a lot,
but the few are problematic.
