Hm. Actually I think the only problem with this is a browser issue.
[ But not any more, see below. ] That attachment is named
"linux-2.4.20-pre9-agp3.patch.gz". Netscape (at least) has absolutely
idiotic behavior when downloading .gz files: it will strip the .gz
extension, but not decompress the file! So when I use Netscape to save
the above, I get:
- -rw-r--r-- 1 hlein users 7023 Oct 28 02:06 linux-2.4.20-pre9-agp3.patch
Which is a bunch of binary crap. But 'file' realizes it's compressed:
$ file linux-2.4.20-pre9-agp3.patch
linux-2.4.20-pre9-agp3.patch: gzip compressed data, deflated, original filename, `linux-2.4.20-pre9-agp3.patch', last modified: Thu Oct 24 19:09:39 2002, os: Unix
And if you rename it to put the .gz back on, and/or gunzip -c it, you
should get what looks like a proper diff file. (I don't know a way for
a server to override this behavior; if anyone does, please contact me
off-list.)
Hm. OTOH, I just tested that with Konqueror (v 3.mumble) and it
segfaults trying to download it. Bad.
[tests]
OK. I was basically reproducing the Content-Disposition header from the
mail, which contains a filename hint. In an email it looks like:
Content-Disposition: attachment; filename="linux-2.4.20-pre9-agp3.patch.gz"
Netscape and at least some other browsers eat that just fine (and take
the filename hint). Konqueror segfaults. If I remove that header, it's
fine, but then there's no filename hint. If I s/attachment;// then
Konqueror doesn't segfault. Netscape 4.8 and MSIE 6sp1 both still grok
the filename hint. Konqueror's handling of the filename hint seems
inconsistent (sometimes doesn't work at all; sometimes thinks the
closing double quote is part of the filename). Still investigating.
But this is better than before, so just committed that change.
I'll file a bug report on Konqueror (the header was admittedly bogus
before, but it shouldn't have caused a SEGV), and try to figure out how
to get filename hints working better for Konq as well.

If these mails don't cross each other, please check if you can if the
other cases you've seen are similar to the above.
