unable to change preferences when run under unity

Unity does not supply Gnome Shell's "Appmenu" and there is no epiphany-globalmenu package or similar. There is no (easily identifiable) way to access the Epiphany browser's preferences, not even with dconf-editor.

$ apt-cache policy $( dpkg -l | grep epiphany | grep ^ii | awk '{print $2}' )
