Obviously, this is a bug. If you find such a thing, please file a bug
report in bugzilla (at http://bugzilla.gnome.org , product: GStreamer),
if possible with a stack trace from gdb.

In this case, it's probably that the height of the input image wasn't a
multiple of 16, which made it crash. Should be fixed in gst-plugins-good
CVS now.

Open temp.tmp in an image viewer of your choice (eog or gimp or
whatever)?
