#4 Fetching element parameter that hasn't been set crashes

[Todd Fischer]

Looks like something doesn't handle a null pointer very well.
The following steps should recreate the error.
gstd &
gst-client create " filesrc name=f ! jpegdec ! ffmpegcolorspace ! xvimagesink"
gst-client -p /com/ridgerun/gstreamer/gstd/pipe0 get f location string
