when seeking really quickly in my app, i sometimes observed
GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed
i could reproduce this after about 40 seek operations on an mkv file within 30
seconds. i got a backtrace:

(object)' failed
(enigma2:2623): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT

Program received signal SIGTRAP, Trace/breakpoint trap.

when continuing, it goes on with
(enigma2:2623): GStreamer-CRITICAL **: gst_object_unref: assertion `((GObject
*) object)->ref_count > 0' failed
(enigma2:2623): GStreamer-CRITICAL **: gst_clock_get_time: assertion
`GST_IS_CLOCK (clock)' failed
and a couple more
(enigma2:2623): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT
(object)' failed
and
(enigma2:2623): GStreamer-CRITICAL **: gst_object_unref: assertion `((GObject

to eventually segfault out
none of my proprietary elements is messing with the clock.
