The Gtk+ assumtion is that popup is done on key down, not key up, i.e.:

(global-set-key
 [(meta control down mouse-3)] ;just some free key
 #'foo)

It is very strange to popup a menu on key up.  From the Gtk+ point of view, 
that corresponds to popping up without a mouse click, hence the error.  I have 
checked in a fix in trunk.
