I think this is really a special case of bug 623922.  Specifically, if the width of the menulist container is so narrow that the ellipses can't be shown, then nothing gets displayed.  When using the Ubuntu font, nothing is shown.  Once I change it to Cantarell (default Gnome 3 font), it shows ellipses.
