Ok, figured it out for myself. For the archive:

    gdkwin = gtk_text_view_get_window (GTK_TEXT_VIEW (widget),
                       GTK_TEXT_WINDOW_TEXT) ;
    gdk_drawable_get_size (GDK_DRAWABLE (gdkwin), &x, &y) ;

    gtk_text_view_window_to_buffer_coords (GTK_TEXT_VIEW (widget),
                       GTK_TEXT_WINDOW_TEXT, 0, y, &x, &y) ;
    gtk_text_view_get_iter_at_position (GTK_TEXT_VIEW (widget), &iter, NULL, x, y) ;

    last_line = gtk_text_iter_get_line (&iter) ;

Cheers,
Erik
