Comment 7 for bug 733309

On the equivalent side for Kubuntu we added appmenu-gtk to our seeds directly, so it could be added as a dependency of the ubuntu desktop seeds.

The widgets which use dbusmenu could recommend it, indicator-appmenu recommends appmenu-gtk, it could also recommend appmenu-qt.

It could also be made a recommendation of qt itself, I don't see much disadvantage in this, it's just inconsistent with what is currently done.
