bug in NSMenu

[Benhur Stein]

Hi all!

While loading a gmodel that contains a menu using gnustep's snapshot
of friday, the program dies with an exception (invalid index) inside
[NSMenuView itemChanged].
The problem seems to be that NSMenuView is getting a notification that
an item has been changed before getting the notification that the same
item has been inserted.
[NSMenu insertItem:atIndex:] calls [NSMenuItem setMenu:] and only after that  
it sends NSMenuDidAddItemNotification.
The problem is that [NSMenuItem setMenu:] calls [NSMenu itemChanged:],
which sends NSMenuDidChangeItemNotification.

Sorry, didn't have time to try correcting the code.

The backtrace just before the exception:
