That approach doesn't bring the same hazards of gst_bus_poll ?

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBus.html#gst-bus-poll

"You should never use this function, since it is pure evil. This is
especially true for GUI applications based on Gtk+ or Qt, but also for any
other non-trivial application that uses the GLib main loop. As this function
runs a GLib main loop, any callback attached to the default GLib main
context may be invoked. This could be timeouts, GUI events, I/O events etc.;
even if gst_bus_poll()<http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBus.html#gst-bus-poll>is
called with a 0 timeout. Any of these callbacks may do things you do
not
expect, e.g. destroy the main application window or some other resource;
change other application state; display a dialog and run another main loop
until the user clicks it away. In short, using this function may add a lot
of complexity to your code through unexpected re-entrancy and unexpected
changes to your application's state."
