Comment:
Thanks Ariel :) Another problem is that "Empty Trash" is among the few
items that *don't* have an icon next to them (at least in breezy, which
I'm running right now), and this contributes to make "Empty Trash" less
noticeable, although it is the action an user most probably wants when
opening this menu.
