GTK errors after Remove and Insert sub-menu item

[mart-k]

The attached program shows GTK-CRITICAL errors
reported when manipulating an item in a menu, using
RemoveItem and InsertItem, the item with a problem is
a sub-menu.

The program sets up a simple menu with an item with a
sub-menu. The sub-menu item is removed and reinserted
and then further manipulated. During this subsequent
manipulation get errors for removing items from the
sub-menu and for inserting to the main menu.

I can see Gtk-CRITICAL's also in 2.8.7

I found this bug in trunk some 6 months ago and submitted a patch to it. So it should be corrected there.

So it would need backporting.
