Original commit message from CVS:
* ext/gconf/gstgconfaudiosrc.c: (gst_gconf_audio_src_init),
(gst_gconf_audio_src_dispose), (do_toggle_element):
* ext/gconf/gstgconfaudiosrc.h:
Remove gconf notify hook when the gconfaudiosrc element is
destroyed, otherwise the callback may be called on an
already-destroyed instance and bad things happen. Should fix
#378184.
Also ignore gconf key changes when the source is already running.
