[Pkg-mailman-hackers] Bug#450399: mailman HTML archives drop MIME parts with no headers

[Daniel Kahn Gillmor]

Package: mailman
Version: 2.1.9-8
Severity: normal
Tags: patch


Mailman appears to create a faulty HTML archive page of any message
which has a part with no header (most MIME parts have at least a
Content-Type: header, but RFC 2045, section 5.2 suggests that it's not
a requirement).  Any headerless MIME part is stripped and not
displayed.

This is discussed upstream here:

  https://sourceforge.net/tracker/index.php?func=detail&aid=759841&group_id=103&atid=100103

The word is that it's going to be fixed in mailman 2.1.10, though that
isn't even in beta yet.

The patch against 2.1.9 seems pretty minimal:

Thanks for maintaining mailman in debian.
