Please fill a ticket with this information.
If you have log files, is better, and a link to the file you are using
where you have the problem.
If you can try do:

gst-launch -v playbin

(with the problematic file)
this can help us to know if is a error in the activity or in the gstreamer

Also, we have gst-launch-0.10 and gst-launch-1.0, please test both.
