[AMaViS-user] DKIM: Headers signed twice?

On outgoing mails, I noticed that the DKIM headers inserted by
amavisd-new look like that:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=incertum.net; h=
        user-agent:in-reply-to:content-transfer-encoding
        :content-disposition:content-type:content-type:mime-version
        :references:message-id:subject:subject:from:from:date:date
        :received:received:received; s=2007; t=1271446098; bh=DmklXs6cV2
        9nE5nZkyU6E1NrclzUZQG5M3cYwm9c1rc=; b=jKiW55408hyTqQXHQiQz25VtM1
        quWuFFyo1mrhiLKWkAjwfZkNr8ON0kNiT1ZVO/zWXoPR4DJHuKMBSTrU9cwBPFb+
        KJednFiMuToYRmHhxaOZNh2nwHFYRI2tEgLnZoiZM4aG4pMXaw+xxVyA5qITRvjw
        wxqjVqNQt96Zlqylg=

As you might notice, "subject", "from" and "date" appear twice. Is
that normal? Something to worry about? My DKIM related settings are
pretty basic:

$enable_dkim_signing = 1;
dkim_key('incertum.net', '2007', '/etc/mail/2007');
[... bunch of other domain/key pairs ...]

This happens with amavisd-new 2.6.4 and Mail::DKIM 0.32.
