Sorry if I wasn't clear -- I *can* provide backwards-compatible code to
handle the above, but I haven't yet. If you don't care about downgrading
Emacs, I would use the above, but take off the "nnir-namazu-" prefix, ie
just:

(index-directory "/var/lib/namazu/")

Perfect, this is the real bug, thank you. I'll get this fixed soon.
