If i try to reply to a message which is a multi-part MIME formated message
containing a non-text part (e.g. Content-ype: image/gif) it looks okay in the
compose window but when I send it all of the MIME parts are missing!  The
message the recipient sees is a text/plain message whose message body simply
says: "This is a multi-part message in MIME format."  But there are no MIME
parts and, as I said before, the content-type is actually text/plain.

Running Mozilla 1.2.1 on Linux (Redhat 8.0).  Compose in HTML and convert to
plain text during send.  Manually quoted the message (

Reproducible: Always

Steps to Reproduce:
1. using any client, send message with plain text main part and a small gif or
jpg as an attachment.
2. using Mozilla 1.2.1 reply to the message (I don't configure to automatically
quote message)
3. Enter my reply (using html composition window)
4. Manually quote message (Options->Quote Message)
5. Click Send (I am configured to convert HTML to plain text)
6. Read message on original account

Actual Results:  
The reply is a text/plain content-type and contains only one line in the message
body, which says: "This is a multi-part message in MIME format."

Expected Results:  
Shown what I saw in the compose window before hitting the Send button.

Attachment: multi-part/mixed MIME message containing one text/plain part and on image/gif part.

Email message (multipart/mixed) containing one text/plain part and one
image/gif part.  Replying to this message using HTML composition window and
converting to plain text results in message being sent without any of the
context.
