            Status: UNCONFIRMED

         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When I call the following functions for getting the position 

gst_element_query_position (pipeline, GST_FORMAT_TIME, &pos)
gst_element_query_duration (pipeline, GST_FORMAT_TIME, &len)

I see the segmentation fault. 
I am using the helloworld application at path
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-helloworld.html#section-helloworld

in which I have registered the callback for every 1000 ms. In this callback I
call the above functions.
Please tell me what can be possible reason behind this. I have seen with
running the gdb and could see the call back but of no use.
