This seems to crash somewhere inside libkdecore via libproxy. It must
be some libproxy kde integration stuff, perhaps a libproxy kconfig
backend or so? In any case, doesn't look GStreamer-related at first
glance.

You might be able to work around it by setting the 

  GSETTINGS_BACKEND=memory

environment variable when starting the app/gst-launch-1.0

Cheers
