dmarc failure when sending to the list

Hello,

I've enabled DMARC on my domain yesterday (patpro.net with p=none), few hours before posting my question about LogWhy verbosity. When I've sent this first email to the list, I've started to get failure reports.

The mail is sent to subscribers with both patpro.net and opendkim.org DKIM signature, and one of the reports shows headers from this message:

        Authentication-Results: taro.andreasschulze.de;
                dkim=pass (1024-bit key; unprotected) header.d=opendkim.org header.i=opendkim-users-bounce_at_lists.opendkim.org header.b=lvOvWAsu;
                dkim=fail reason="no signature error" (1024-bit key; unprotected) header.d=patpro.net header.i=_at_patpro.net header.b=VXvJ53xD

I can see that people here manage to send DKIM signed email to the list that are properly checked by my server:

        Authentication-Results: rack.patpro.net (amavisd-new);
                dkim=pass (1024-bit key) header.d=opendkim.org header.b=3LBzXNHA;
                dkim=pass (4096-bit key) header.d=andreasschulze.de header.b=f0/7Sas7

Is this a problem on my side?
