It does. gdk_notify_startup_complete() is automatically called when
the first window is displayed by an application, since Gtk+2.2. Look
at the GtkWindow class if you need to override the automagic handling.

Setting StartupNotification to True in Geany's .desktop makes
launching Geany from the panel work as expected.
