Here is an article that exhibits the problem in Gnus for me:

  news.gmane.org gwene.dk.gaffa.anmeldelser.cd:106

Hm. Let me just ngrep what happens when I read it, to see what comes
over the wire..

Oh. Encryption. Great.

Ok, let me telnet:

  $ telnet news.gwene.org nntp

This makes me think that it is Gnus doing this. Hm.

Can I find the right function to edebug? Ok, found it - by trial and error:

 gnus-summary-remove-list-identifiers

is the culprit. It removes "^[A-Z ]*?: " (!)

My elisp fu fails me now, this function:

  (defun gnus-group-get-list-identifiers (group)
    "Get list identifier regexp for GROUP."
    (or (gnus-parameter-list-identifier group)
        (if (consp gnus-list-identifiers)
            (mapconcat 'identity gnus-list-identifiers " *\\|")
          gnus-list-identifiers)))

returns "^[A-Z ]*?: " even though gnus-list-identifiers is nil?!?

Something is setting gnus-list-identifiers behind my back locally, somehow?!

Because if I run: (gnus-group-get-list-identifiers
"nntp+news.gwene.org:gwene.dk.gaffa.anmeldelser.cd") directly, it
returns nil, as I expect.

I can't for the life of me figure out how that happens, when I edebug
the function and do C-h v on gnus-list-identifers, I'm told it is nil.

But edebugging I can see that consp returns t and the function returns
"^[A-Z ]*?: ".

If I change it to:

  (defun gnus-group-get-list-identifiers (group)
    "Get list identifier regexp for GROUP."
    nil)

The summary looks as I expected it to do, nothing removed.

Ok, elisp experts - enlighten me!

  Best regards,

    Adam
