The relevant part is, I think:

(setq gnus-secondary-select-methods
      '((nnml "" (gnus-search-engine
		  gnus-search-namazu
		  remove-prefix "/home/bronger/Mail"
		  index-directory "/var/lib/namazu/"))))

I’m happy to post the rest of my .gnus and .emacs somewhere if
helpful.

In *Messages*, it says:

nnselect-run: gnus-search-run-query on ((search-query-spec (query . +from:aixasset@web.de) (raw)) (search-group-spec (nnml: nnml:KFA-FBL))) gave error (wrong-type-argument stringp nil)
