Bus.AddSignalWatch() requires a running GLib (or Gtk+) main loop
running to work.

On a side note, the playbin element itself implements the
GstVideoOverlay interface as well, so you don't have to wait for a
prepare-window-handle sync message, but can just set things directly on
it and it will proxy it to any sinks later.
