--- Comment #1 from Emanuele Aina <emanuele.aina at collabora.com> 2013-03-28 16:47:29 UTC ---
The following error is due to the fact that in foo.jpg the image data is
preceded by EXIF and XMP metadata and this cause the type detector to fail to
find the width and height of the image.

$ gst-launch-1.0 playbin
uri=http://rygel-project.org/snapshot/testfiles/foo.jpg 

Setting pipeline to PAUSED ...

WARNING: from element /GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0: No

With debug output enabled things go wrong after the following line:
decodebin gstdecodebin2.c:1873:connect_pad:<typefind> caps image/jpeg not
subset of image/jpeg, width=(int)[ 1, 65535 ], height=(int)[ 1, 65535 ]

In fact at that point caps are just "image/jpeg".
