What is really needed her is canberra-gtk-play in both binaries, and under different names, however that would require the desktop files in gnome-session-canberra to have 2 different versions as well. I think we're best off getting canberra-gtk-play built against GTK2 only at this point, and since we will be moving closer to GTK3 in natty+1 then things should sort themselves out from there.
