Mangled "Re:" in i18n subject header

[Phd-users]

Hello!

Look, here is the subject from a mailman-managed
mailing list:

Subject: [Bug]
=?koi8-r?B?UmU6IFtCdWddIFJlWzJdOiBbQnVnXSBSZTogW0J1Z10gUmU6IFtCdQ==?=
 =?koi8-r?B?Z10g8NLPxMHF1NPRINPMwdfRztPLycog28vBxg==?=

Let me decode it:

import sys, email.Header
print email.Header.decode_header(sys.stdin.read())

[('Subject: [Bug]', None), ('Re: [Bug] Re[2]: [Bug] Re:
[Bug] Re: [Bug] \xf0\xd2\xcf\xc4\xc1\xc5\xd4\xd3\xd1
\xd3\xcc\xc1\xd7\xd1\xce\xd3\xcb\xc9\xca
\xdb\xcb\xc1\xc6', 'koi8-r')]

Look how many "Re:"s re there!

The problem arise when Mailman adds list tag (in this
case [Bug]) to an *encoded* header. Mailman must decode
the header and check for "Re:" and list tag in the
decoded header.

All mailing lists that I know are guilty with the bug.
Let Mailman be the first that fixes it! Thank you.

Oleg, have you tried this with MM2.1? I think there's code
in there that tries to decode the header first before
searching for the prefix. I'm not surprised MM2.0 doesn't
do the right thing, but MM2.1 should.

Mailman 2.1 is still in beta. I don't dare to recommend it
to sysadmins - these are not my mailing lists, nor my hosts.
But it's good to know there is a fix. I'll give it a try
when you release 2.1-final.

I'm closing this because I believe it /is/ fixed in MM2.1
and it won't be fixed in MM2.0.x.
