This must be one of the most annoying features I've seen, and poorly 
implemented at that.  I can't imagine any Emacs user wanting this, Every 
Ctrl-press starts the animation, and there are a lot of ctrl-pressing 
going on in Emacs.  I've checked in a fix so that Emacs does not hang, 
that is the best we can do sort of changing GTK.  Other GTK apps don't 
handle this option well either, Gedit does not show the popup menu on 
Ctrl-button-3 when that option is activated (at least not the one in 
Gnome 2.8).

Not entirely true, you do get this for Motif based applications:

Warning:
    Name: popup_menu
    Class: XmMenuShell
    XtGrabKeyboard failed

The option grabs the ctrl key and when GTK can't get that grab, it 
silently refuses to pop up the menu.
