Package: mpack
Version: 1.6-1
Severity: minor
File: /usr/bin/munpack

Nowadays I always get this message
$ munpack big_wei_picture
tempdesc.txt: File exists
DSC00542.JPG (image/pjpeg)
even though there seems to be no tempdesc.txt file anywhere I looked.

I also get this problem with 1.6.1 (while 1.5 works ok). Not always,
but here's a reproducible test case. (I trimmed the message contents
for privacy reasons, hope I didn't break the MIME structure in the
process, but the bogus error is the same.)

According to strace, mpack tries to create (with O_EXCL)
tempdesc.txt twice, so the second one fails.

Hi,

I've just encountered this; for emails that have >1 text part. I suspect
that's triggering this misbehaviour.

(1)  In dealing with Thunderbird-produced eml files that contain
multiple attachments, you encounter the following problems:

     (a)  Each attempt fails because tempdesc.txt already exists (a
"sudo find / -type f -name "tempdesc.txt" proves it doesn't, not anywhere).

     (b)  Thunderbird uses exactly the same name for each attachment,
which is "Attached Message".  You can't do a bulk unpack, since the
attachments will just overwrite each other.  Mozilla now has a bug
report on this.  I see that munoack should append double digits to the
unacked name, but double digitd might not be enough if a lot of files
get moved this way.

     (c)  Mpack and munpack do not recognize the "--help" option.  In
failing to do so,they still give some indication about options, but do
not explain them.  Fortunately there is a man page for mpack and
munpack, so if the user knows about man, they can get some answers.

This has been flagged as a minor' problem.  I disagree.  As matters
stand, munpack will not do its job at all.  That problem with
tempdesc.txt won't let it.

Regards.
