Description mabiorc 2011-08-24 00:01:22 UTC 
I'm using gst-plugins-base-0.10.32.2/tests/icles/playback/test7.c to
test the gap-less playback feature of playbin2 but it is not working.

Running the unmodified example plays great for the first uri, executes
the about_to_finish_cb properly, but when it is supposed to play the
next URI, throws the message bellow:
(test7:7165): GLib-GObject-CRITICAL **: g_object_set: assertion
`G_IS_OBJECT (object)' failed

Same behavior on 0.10.35 (on gst-plugins-base-0.10.35/tests/icles/playback). Some times we get a SIGABRT and other times (less frequent) a SIGSEGV.

Here is the backtrace on the 0.10.35 getting a SIGABRT:
