Ubuntu Gutsy gibbon 7.10 amd64
(I have installed p7zip p7zip-full rar unrar)
I tried to unzip multipart file archive (Fink.zip Fink.001 Fink.002 Fink.003).

Right click -> extract here and it outputs this error:

warning [/home/forger/Desktop/Fink.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).
file #1: bad zipfile offset (local header sig): 4
file #2: bad zipfile offset (local header sig): 27969969
file #3: bad zipfile offset (lseek): 49012736

Then tried the command: 7za x Fink.zip
with this error:

7-Zip (A) 4.51 beta Copyright (c) 1999-2007 Igor Pavlov 2007-07-25
p7zip Version 4.51 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)
Processing archive: Fink.zip
Error: Can not open file as archive

I even tried unrar / rar and they don't support the file. It looks like they can't handle multipart zip files.
The multipart files were extracted successfully in a Windows environment, using Winrar 3.71
