Please describe the problem:
Invoking a pipeline with a filesrc feeding a png image to ffdec_png generates
errors rather than joy.

Steps to reproduce:
1. Invoke: gst-launch filesrc location=/home/me/pic.png ! ffdec_png
2. See error below

Actual results:
Setting pipeline to PAUSED ...
Pipeline is PREROLLED ...
ERROR: from element /GstPipeline:pipeline0/ffdec_png:ffdec_png0: Internal
GStreamer error: negotiation problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
