I've built a pipeline (filesrc, oggdemux, ffdec_mpeg4, and a specific sink) to
read an ogm video file (with xvid + vorbis streams).

When I set the pipeline to PAUSED, it hangs when I call gst_element_get_state.
Here is the backtrace:

you can download the program I use there:

http://www.maths.univ-evry.fr/pages_perso/vtorri/files/gstreamer_test_seek/gst_seek.tar.bz2

just untar the archive, go into gst_seek and run make. It install the sink in
~/.gstreamer-0.10/plugins and create the test program seek_ogm. Pass the ogm
file as an argument to that prog.

The file I use :
