Using Gnus, doing 'G G' on a nnmaildir group gives me this error:

```
nnselect-generate-artlist: gnus-search-run-query on ((search-query-spec (query . subject:meditation) (raw)) (search-group-spec (nnmaildir:email archive clients crypto-archive crypto-sent drafts inbox git git-l10n job-hunting list medical penpal poker sent shopping software spam wellness writing) (nndraft nndraft:delayed) (nndraft:nnmaildir:email nndraft:drafts))) gave error (wrong-type-argument stringp nil)
Group nnselect:nnselect-878qv99nf2.fsf contains no messages
```

The relevant configuration of `~/.emacs` is:

```
(setq message-kill-buffer-on-exit t) ;; C-c C-c kills the buffer
(setq gnus-check-bogus-newsgroups t) ;; delete bogus newsgroups at gnus startup

;;; open gnus in topics mode
(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)

;;; lines with time
(setq gnus-summary-line-format "%U%R%z%I %4L %(%[%-25,25D %-23,23f%]%) %s
")

;;; order threads by most recent date
(setq gnus-thread-sort-functions '(gnus-thread-sort-by-most-recent-date))

;; hide summary lines of articles that have scores lower than this
(setq gnus-summary-expunge-below -9)


(setq gnus-select-method
      `(nnmaildir "email"
                  (directory ,(expand-file-name "~/.mail"))
                  (nnmaildir-directory ,(expand-file-name "~/.mail"))))

(setq gnus-message-archive-group '((if (message-news-p) "list" "sent")))
(setq nndraft-directory (expand-file-name "~/.mail/drafts"))

(setq message-directory (expand-file-name "~/.mail"))
(setq gnus-directory (expand-file-name "~/.emacs.d/news"))
(setq nnfolder-directory (expand-file-name "~/.mail/archive"))
(setq nnfolder-directory "~/.mail/archive")
(setq nnfolder-active-file "~/.mail/archive/active")
(setq gnus-server-alist '(("archive" nnfolder "archive"
                           (nnfolder-directory "~/.mail/archive")
                           (nnfolder-active-file "~/.mail/archive/active")
                           (nnfolder-get-new-mail nil)
                           (nnfolder-inhibit-expiry t))))
(setq mail-default-directory "~/.mail")
(setq smtpmail-queue-dir "~/.mail/.queued-mail")

;; gnus search
(setq gnus-search-default-engines
      '((nnimap . gnus-search-imap)
        (nnmaildir . gnus-search-find-grep)
        (nnselect . gnus-search-nnselect)))
```

Gnus is running good, and I am trying to add searching capabilities to
my, already organized, email.

Doing an epheremal search using 'G G' with point on a nnmaildir group is
giving me the error above. Doing the same of my Topic of my nnmaildir
groups also give me this error.

My GNU system has `grep` installed. I don't want to do searches on my
maildirs with any other searching methods/executables.





Did not crash.

IIRC, this is because the grep method does not change to the maildir
directory properly.  Since I do not know the maildir terminologies well,
if you say G G on a group named "nnmaildir+mail:spam" it does not
search in ~/.mail/spam/ but in ~/.mail/ using find with -maxdepth
1, which obviously fails.

[ AFAIR, the workaround I posted in bug#72196 does not work for the grep
  method.  ]
