State changes to GST_STATE_NULL not being communicated.

[Yogesh Marwaha]

Hi,

Just re-wording my problem once again (keeping it simple - perhaps).

When I try to set playbin (playing a local file) to GST_STATE_NULL, playback 
stops[1] but no communication (i.e. GST_MESSAGE_STATE_CHANGED message) 
regarding change of state is received by the watch (on the playbin).

That is to say, when I put the playbin to GST_STATE_PLAYING I get messages of 
all state changes (GST_STATE_READY > GST_STATE_PAUSED > GST_STATE_PLAYING), 
but when I put the playbin to GST_STATE_NULL (which is in state 
GST_STATE_PLAYING), I get no such messages (i.e. GST_STATE_PAUSED > 
GST_STATE_READY > GST_STATE_NULL is not received)

I'm using gstreamer/gstreamer-plugins-base 1.0.6.

Any idea about this?

[1] I can no longer hear from the speaker :-) and I can once again put the 
pipeline to play/pause state and receive messages of all state changes 
(GST_STATE_READY > GST_STATE_PAUSED > GST_STATE_PLAYING)
