As far as I can tell, this is exactly the same package list as pacman -Qe gives, but I can't be certain because for some reason "pacman -Qe > blah" doesn't behave the way you'd expect and I'm too lazy to cut and paste.

Produces the same list. Which isn't its fault, actually, it's yaourt's for passing only Qt to pacman.
