[arch-general] pacman -Qdt

I've been using this very nice command after removing a lot of stuff, and it's great to find orphans. But I think there are some issues.. For example I just installed python2-tinkerer from aur, which needs python2-sphinx. I had installed python-sphinx and they interfere with each other. So I removed python-sphinx and reinstalled again. All the dependencies are satisfied and tinkerer is installed correctly. But now look at what I get: # pacman -Qdt python-jinja 2.6-2 python2-sphinx 1.1.2-2 which seems wrong to me. Is it maybe that packages from aur don't have the same weight when checking for reverse dependencies?
