gstreamer crashed when playig with uri=file:NULL using playbin

[Sujith reddy]

Hi ALL,


This are the error snippets found .
*error snippets are:*

* GStreamer-CRITICAL **: gst_poll_get_read_gpollfd: assertion 'set != NULL'
failed

 GStreamer-CRITICAL **: gst_bus_create_watch: assertion 'bus->priv->poll !=
NULL' failed

 GStreamer-CRITICAL **: Creating bus watch failed
*


this is the sample code what i am using ,when playing with uri=file:NULL  

please correct me if anything wrong.
