This appears to be the same bug.  The solution is to launch a DBus
session bus *before* starting emacs (or any other gtk3 programs for that
matter), IOW:

$ eval `dbus-launch --sh-syntax`
$ emacs-X11 &

The first command should be added to the beginning of your
~/.startxwinrc, if you're using startxwin (or its shortcut) to start the
X server.

BTW, please be sure to reinstall dconf-service, that's not the problem,
and you're going to need it in the "new world order" of GNOME 3.

I cannot reproduce this.  Does installing font-cantarell-otf help?
Perhaps another font?
