Gnus and notmuch

[Alexis Praga]

Hi guys,

I've tried to setup Gnus to use notmuch as a search engine
(configuration below) but running G G on the group buffer yields an
error "(wrong-type-argument number-or-marker-p nil)" (backtrace below).

My setup uses 2 maildir. If I set only the "gmail" one, I can run
searches but there are never any results. Using the "free" one, I have
the previous error.

Any help appreciated !

Configuration :
>(setq gnus-select-method '(nnnil "")
>      gnus-secondary-select-methods
>      '((nnmaildir "gmail" (directory "~/mail/gmail")
>                  (gnus-search-engine gnus-search-notmuch)
>                  (config-file "/home/alex/.notmuch-config")
>                   (get-new-mail nil)
>                  )
>       (nnmaildir "free" (directory "~/mail/free")
>                  (gnus-search-engine gnus-search-notmuch)
>                  (config-file "/home/alex/.notmuch-config")
>                   (get-new-mail nil)
>                  ))
>      gnus-search-use-parsed-queries nil) ; Emacs 28

Config: GNU Emacs 28.0.50
