Thanks for the tip.  Following your email, and after a bit of digging, 
I've discovered another way to completely take care of this nonsense.  
Basically, it's only a matter of removing a set of packages from the 
system.  These packages are:

appmenu-gtk3
appmenu-gtk
appmenu-qt

After removing these packages from the system, Unity starts handling 
menus in a sane manner.

It does look like that.  I don't know what the people behind Unity were 
smoking at the time.

That's nice to know, and it will come in handy next time I need to pull 
a similar stunt.


Thanks for the help,
