it doesn't matter the keyboard layout.
I'm using the French fr-latin9 layout but it also happens in qwerty GB layout.
I don't use the GNOME desktop, so I haven't Unity (I use Fluxbox).
I'll try with the guest session and keep you updated but since it already happens in the login screen (lightdm-gtk-greeter) as well, I think it can already be considered as a bug.
