Heh! We take every chance to blame that we can :)

So I looked into it -- the file is strange. It does read fine in *nix land though (I have FreeBSD on a virtual machine). You may be interested in the list of files:

Back in Windows, when I try to open DBD-Pg-2.10.0-Perl5.8.tar.gz with PowerArchiver, it does detect the duplicate files, but the entire archive has been flattened (i.e., directories are empty & plain files appear as duplicates in the same dir). This is the same thing you're seeing.

You mentioned using an old version of WinZip. Perhaps IZArc could help?
