338902 - htab appears in attachment filename

Status: RESOLVED DUPLICATE of bug 240924

(SeaMonkey :: MailNews: Message Display, defect)

Description

[John Coonrod]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.2) Gecko/20060404 SeaMonkey/1.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.2) Gecko/20060404 SeaMonkey/1.0.1

When mail messages contain attachment filenames in folder headers containing htab, seamonkey embeds an htab in the filename - making an illegal filename - instead of treating htab as whitespace as it should.

Reproducible: Always

Steps to Reproduce:
1. Send an email message with a filename longer than 72 characters that includes spaces.
2. Try to save that attachment
3 [review].

Actual Results:  
Seamonkey will attempt to create a filename including an htab that windows cannot save.

Expected Results:  
whitespace converted to a single space

Other bugs have noted that this same problem affects processing of other headers.

Without seeing the actual MIME headers of the part in question, I can't state whether this actually is a bug.  As noted at bug 240924 comment 6, the mail client is supposed to leave embedded whitespace in a header when it unfolds it.
The sending client shouldn't be folding the filename without using some 
encoding scheme (RFC 2047 or RFC 2231).

OK, I've tracked down what client causes this problem - it is always from Microsoft Outlook Express for Mac - so, I think we'd better accommodate it rather than hope that Microsoft will fix it. Here is an example of a folded title header with the same problem.

	and other things

Seamonkey displays a little black mark in the message list instead of white space. What Seamonkey should do, I think, is simply replace all HTABS with blanks in headers, or in the file save component and subject lister.

Is this bug about the Subject header, or is it about attachment filenames?
Comment 2 is about the problem at bug 240924 (where you have already posted a comment).  If this bug isn't about the attachment filename case, mark this bug 
as a dupe of that.  If it *is* about the attachment filename case, please provide sample headers showing that problem.

No response from reporter, duping.
