From gtk.gdk.theads_init reference: Signal handlers are automatically invoked within a gdk_threads_enter() and gdk_threads_leave() function pair by GTK so the gtk.gdk.threads_enter() and gtk.gdk.threads_leave() functions should not be called within a Python signal handler or the application will deadlock. However, idle, timeout and input handlers are executed outside the GDK global lock (GGL) so these should use the gtk.gdk.threads_enter() and gtk.gdk.threads_leave() functions if PyGTK methods or functions are called.
