Was it filed in the bug tracker for GTK+? [ currently bugzilla.gnome.org ]
If not, it was, for all practical purposes, not reported.

BTW - the proper place for discussion of GTK+ issues is gtk-list.
(Or gtk-devel-list if you want to suggest changes to GTK+)

Errr, sensitivity a completely different issue (probably a bug,
though a very hard one to fix.) Feel free to file that one in the 
bug tracker.

I see no problems with window being mapped - as the attached variant of
your test case shows.

[ Hint, add -Wall to you flags when you compile programs like this. ]

============

#include <gtk/gtk.h>

int active_button(gpointer foo)
{
	gtk_widget_set_sensitive((GtkWidget *)foo, 1);
	g_print("button activated!\n");
	return 0;
}

int main (int argc, char **argv)
{
	GtkWidget *window;
	GtkWidget *button;

	gtk_init(&argc, &argv);

	window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

	gtk_widget_set_usize(window, gdk_screen_width(), gdk_screen_height());

	button = gtk_button_new_with_label("Hello!");
	
	gtk_container_add(GTK_CONTAINER (window), button);

	gtk_widget_show(button);
	gtk_widget_show(window);

	gtk_main();

	return 0;
