Hmm, just "error"?

No, this is a misrepresentation of the actual error. I get this:

$ unzip pack.zip 
Archive:  pack.zip
warning [pack.zip]:  zipfile claims to be last disk of a multi-part archive;
  attempting to process anyway, assuming all parts have been concatenated
  together in order.  Expect "errors" and warnings...true multi-part support
  doesn't exist yet (coming soon).

which is a lot more than the simple "error" that you wrote.

By contrast, file-roller says this in my system:

7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
p7zip Version 9.20 (locale=es_ES.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)

Error: /tmp/pack.zip: Can not open file as archive

Errors: 1


which is a lot less helpful than the message given by unzip, as it
does not even warn that the file is the first one in a multipart archive.


I'm reassigning this to file-roller as I think the error message could
be improved there.

Thanks.
