[Yogesh Tyagi]

Hi,

On a development board when I am trying to run "gst-inspect" command , I
get this error:

CPU: 0 PID: 2683 Comm: gst-plugin-scan Tainted: G      D    O 3.12.17 #1

and kernel crash. Here is the log:

I am using gtsreamer 0.10.38.Although there is no issue in media playback
with gst-lauch. Can somebody please provide some pointer to me to debug
this issue further?

Thanks,
Yogesh
