User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624 Netscape/7.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030807

Mozilla will not display the body of a news article, on, if the
article contains an attachment (or other multipart MIME). Only the headers are
displayed. This occurs whether or not "View->Display Attachments Inline" is

The entire contents of the message, including multipart MIME, *are* displayed if
CTRL-U is pressed or if "View->Message Source" is selected.

When I saved one of the offending articles to a local file, Mozilla exhibited
the same display problem on the local copy. I will attach a copy of the
offending article to this bug report after submission.

Note:I originally found the problem in Netscape 7.1. Then, after "asking
around", I heard from Richard Owlett <>. He found the
problem also exists in Moz 1.4 [ Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.4) Gecko/20030624 ] and NS 4.6.

Reproducible: Always

Steps to Reproduce:
1. Visit the URL news://$i84$
1. Copy the attached article to a local file. E.g., /tmp/article.eml
2. View the local article using Mozilla. E.g., file:///tmp/article.eml

Actual Results:  
Headers for the article are displayed, but no message body (or attachment).

[Type CTRL-U to see the full contents of the message.]

Expected Results:  
Display the message body (and optionally the attachment).

Example news article that fails to display correctly

This is an example of a simple text article with a simple text attachment.
The Content-type header is trashed; it should specify a boundary.

Content-Type header from the original message in the Sent folder

This is a subset of the headers from the original message in my NS 7.1 "Sent"
folder. Note that the Content-Type header did specify a boundary, but NS 7.1
put it on a separate line. Perhaps, the news server didn't like that and
dropped the boundary line? I don't know.  However, it seems that Mozilla could
at least display the contents as simple text and a warning message status, if
it reads a bad Content-Type header.
