The exact Subject: header (from the file, not notmuch) is:
Subject: [BIBLIST] Digitaliseringensprojektens skadliga f=?ISO-8859-1?Q?=F6rk=E4rlek_f=F6r_?= PDF-formatet

Other potentially interesting headers are:
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:17.0) Gecko/20130106
            Thunderbird/17.0.2
MIME-Version: 1.0
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

(formatted as they appeared in the mail file)
