Since commit 7fad12c59b3c65665c10050e800d1d7ad5a2e056, I have
problems getting namazu-based mail searching working.  My
configuration says:

In .emacs:

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

In .gnus:

(setq gnus-secondary-select-methods '((nnml "" (nnir-search-engine namazu))))
;; I have not set gnus-search-use-parsed-queries.

This results in "Group nnselect:nnselect-87sg78bdzr.fsf contains no
messages" error when I hit "G G" in the group buffer and enter a query
string.  Besides, the namazu executable is not called at all.  The same
behavour I get if I don’t configure namazu at all in Emacs/Gnus.
