Bug in menu sensitivity.

[Dave Cole <dave dccs com au>]

I just noticed some buggy behaviour in the menu code which allows you
to select an insensitive menu item.  Here is a program which
demonstrates the bug.

{
    fprintf(stderr, "I am insensitive - you should not be able to select me!\n");

    fprintf(stderr, "Please follow instructions!\n");

    gtk_widget_show_all(top);

    gtk_main();
    return 0;
