Original commit message from CVS: * ext/pulse/pulsemixer.c: (gst_pulsemixer_change_state): * ext/pulse/pulsemixerctrl.c: (gst_pulsemixer_ctrl_subscribe_cb), (gst_pulsemixer_ctrl_open), (gst_pulsemixer_ctrl_new), (gst_pulsemixer_ctrl_free), (gst_pulsemixer_ctrl_timeout_event): * ext/pulse/pulsemixerctrl.h: * ext/pulse/pulseprobe.c: (gst_pulseprobe_open), (gst_pulseprobe_enumerate), (gst_pulseprobe_new), (gst_pulseprobe_free), (gst_pulseprobe_needs_probe), (gst_pulseprobe_probe_property), (gst_pulseprobe_get_values): * ext/pulse/pulseprobe.h: * ext/pulse/pulsesink.c: (gst_pulsesink_init): * ext/pulse/pulsesrc.c: (gst_pulsesrc_init), (gst_pulsesrc_delay), (gst_pulsesrc_change_state): Improve debugging a bit by including the parent object in pulsemixerctrl and pulseprobe objects and using GST_WARNING_OBJECT instead of GST_WARNING. Use the parent GObject subclass instead of a random struct as GObject parameter for G_OBJECT_WARN_INVALID_PROPERTY_ID. This fixes a crash when probing for another property than "device".
