In Qt port, WebKit node objects will be created and destroyed in the main
thread only. So here mediaplayer element also getting created and destroyed
in main thread. Is the page active When u r destroying the playback
instance ? Normally this mediaplayer object is destroyed after page/view is
deleted, by WebKit.
