I am unable to duplicate this problem. I see the problem in the archive index at http://lists.isfahanlug.org/pipermail/supervisors/2014-November/thread.html. I have downloaded the http://lists.isfahanlug.org/pipermail/supervisors/2014-November.txt.gz file (which by the way is doubly gzipped[1]) and can see the several messages therein with empty Subject: header, but when I process these through the pipermail Archiver, they get archived with a Subject: of 'No subject' (even in the 2014-November.txt file) and properly indexed. This may be a Debian Mailman bug, but it appears that this doesn't happen with standard GNU Mailman. You could try filing a Debian bug and see what they say. If you have access to the /var/lib/mailman/archives/private/supervisors.mbox/supervisors.mbox file, I would like to see at least one of these improperly indexed messages from that file. [1] The contents of http://lists.isfahanlug.org/pipermail/supervisors/2014-November.txt.gz is a file named 2014-November.txt, but this is actually a gzipped file which needs to be renamed 2014-November.txt.gz and gunzipped again to get the plain text. This may also be a Debian bug (I've seen it before). ** Changed in: mailman Importance: Undecided => Medium ** Changed in: mailman Status: New => Incomplete ** Changed in: mailman Assignee: (unassigned) => Mark Sapiro (msapiro) -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1388614 Title: archive problem when an email got not subject To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1388614/+subscriptions

Here's the file you asked (only couple of emails that produce this bug). I will ask their sys admin to ungunzip that file again to see that would solve the problem or not. ** Attachment added: "mbox file" https://bugs.launchpad.net/mailman/+bug/1388614/+attachment/4253181/+files/s... -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1388614 Title: archive problem when an email got not subject To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1388614/+subscriptions
