I've got file(1) from 'stable':

file:
  Installed: 4.12-1
  
The errors are not crashing amavisd-new, it keeps running.

There appear to be three messages associated with each of these. The
first is the Decoding of part-0000x gzip failed, error running
decompressor. The second is the TROUBLE in check_mail,
decoding2-get-file-types FAILED: 'file' utility failed status=255.
(these are quoted above), and then the third is:

Jul 30 06:35:21 buffy amavisd-new[29274]: (29274-26) PRESERVING
EVIDENCE in /var/lib/amavis/tmp/amavis-20060730T062903-29274

I had a look at this one, it exists, and this one actually looks like
a genuine email, with a gnumeric attachment, the email body has a
bunch of portugese characters in it.

I looked at another one, this one happened to also be a legitimate
email, didn't have UTF text, but had a jpg attachment.

The directory contains an email.txt and a parts directory. How can I
take that to another system and test it?

I see, its a bit of a process to upgrade, and would mean that I'd have
to disable virus protection while I sort out the configuration changes.

I've actually got that change in place already, its the first thing I
tried when I tried to fix this problem.

There is a file(1) from backports (4.17-0bpo1), I'm going to install
it and see how it goes.
