Gstreamer and Qt

[miskol]

I got a problem with gstreamer and -QT- Qt.
I started with this example http://wiki.forum.nokia.com/index.php/Sample_application_for_investigating_GStreamer_pipelines
and all works fine
gstreamer make callbacks and notify application about state changes

But as I want to move my application to QML
-QT- Qt main thread move from QCoreApplication(example) to QApplication(created with qt wizzard)
and all notifications from gstreamer stop.

I investigate this problem and it should be related to GTK main loop

Any idea how to solve this problem??
