Also try this:

gst-launch-0.10 -v filesrc location=test.png ! pngdec ! ximagesink

Use a PNG file that differs from your X display in bpp to get this proper
failure (with gst 0.10.14 from Ubuntu Gutsy):

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/pipeline0/pngdec0.src: caps = video/x-raw-rgb, width=(int)320,
height=(int)240, bpp=(int)32, framerate=(fraction)0/1, depth=(int)32,
endianness=(int)4321, red_mask=(int)-16777216, green_mask=(int)16711680,

ERROR: from element /pipeline0/pngdec0: Internal data stream error.
Additional debug info:

ERROR: pipeline doesn't want to preroll.

With CVS gst I get this instead:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/pipeline0/pngdec0.src: caps = video/x-raw-rgb, width=(int)320,
height=(int)240, bpp=(int)32, framerate=(fraction)0/1, depth=(int)32,
endianness=(int)4321, red_mask=(int)-16777216, green_mask=(int)16711680,

/pipeline0/pngdec0.src: caps = NULL

Note how data seems to flow up to proper EOS, however the caps on
ximagesink:sink are never set.  The debug log shows some more weirdness, for
example the EOS message gets out _before_ pngdec errors out with
not-negotiated.  Even more strange: I can't reproduce this with jpegdec at
all...
