bug#65196: 28.2; gnus-group-make-nnir-group always returns "no messages"

[Loris Bennett <loris.bennett@fu-berlin.de>]

After upgrading Debian from 11 to 12, gnus-group-make-nnir-group always
says that the search group contains no messages, even though there are
in fact messages in the original group which contain the string searched
for.

In *Messages* somethin like the following will appear:

  Opening server fu_exchange
  Searching nnimap+fu_exchange:HPC...done
  Group nnselect:nnselect-87jzu3z7wb.fsf contains no messages

The configuration in init.el is as follows:

  (setq user-mail-address "loris.bennett@fu-berlin.de")

  (setq message-send-mail-function 'smtpmail-send-it)
  (setq smtpmail-smtp-server "mail.zedat.fu-berlin.de")
  (setq smtpmail-smtp-service 587)

  (setq gnus-select-method '(nntp "news.fu-berlin.de"))
  (setq gnus-secondary-select-methods
        (quote
         ((nnimap "fu_exchange"
                  (nnir-search-engine imap)
                  (remove-prefix "nnimap")
                  (nnimap-address "mail.zedat.fu-berlin.de")
                  (nnimap-record-commands t)
                  (nnimap-inbox INBOX)
                  (gnus-message-archive-group "nnimap+fu_exchange:Gesendete Elemente")))))

The same problem occurs with nntp groups (not configured in this test).

Unfortunately that is all the information I can provide, although I can
see that it is probably insufficient to identify the problem.
