> ambiguous call; both glib.g_thread_new() Really a funny bug: That proc was missing for my version of gobject-introspection, so I added it manually as a user from Japan needs it for the libnice example. But your version of gobject-introspection already provides it. Should be fixable.
And to make this post matching the initial question: I am working on GTK3 and GTK4 bindings still from time to time, since 5 years now. Indeed a bit boring.
