434633 - "Re:" added even when already present when replying to a message opened from a MIME digest

Status: VERIFIED DUPLICATE of bug 387061

(Thunderbird :: Message Compose Window, defect)

Description

[David Woolley]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14
Build Identifier: 2.0.0.14 (20080421)

If you use File|Attachments|Open on a message within a MIME digest (e.g. those generated by Pipermail at mailman.qth.net).  Thunderbird adds Re: at the beginning of the subject even if there was already one there.  It doesn't do this when replying directly to a message.

Reproducible: Always

Steps to Reproduce:
1.Open a MIME multipart/digest message (I do this with double click for its own window, but this is not necessary)
2.Select File|Attachments|Open on a message in the digest that already has Re: at the start of the subject.
3.Select Reply All on that message, but Reply also produces the same result.
Actual Results:  
Subject has bogus Re:

e.g.

Re: Re: [Elecraft] RFTB Sunday Night

when the original subject was

Re: [Elecraft] RFTB Sunday Night

Expected Results:  
Re: [Elecraft] RFTB Sunday Night

The erroneous Re: is the first one, as some mailers use RE: and this appears second.

The specific digest used in this example was:

Elecraft Digest, Vol 49, Issue 40

Confirming on trunk.

It looks like this one duplicates #387061, although that one says Re: is duplicated when it is actually added.

Indeed.
