Have you tried the following, should be the simplest way to try gstreamer:

gst-launch playbin2 uri=file:///test.mp4

Two more things:
1. Can you please paste the bootlog?
2. Dizzy uses FSL kernel 3.10.17 for sabresd, where gstreamer is known
to work for most users. Can you try a standard, "out-of-the-box" build
on your sabresd and share the results? I'm regularly doing
test/comparison builds for sabresd and haven't seen any oddities like
the mentioned above.
