I'm using the most recent git version of emacs, updated ten minutes ago
or so. I (require 'package), then add-to-list both Melpa and Marmalade
to package-archives. I have a dozen or so packages installed already,
from ELPA, Melpa, and Marmalade.

The command `list-packages' then gives me a *Package* buffer in which
all installed packages are marked as "unsigned", in a bright red face,
and the "archive" column is empty. Getting info on any of these
installed packages shows a *Help* screen where the "Archive" heading
reads n/a, but "Version" obviously matches on of the versions mentioned
in "Other versions". I've attached a screenshot which should make all of
this obvious. Apparently it's not supposed to be like this.

Thanks,
Eric
