i'd bet that the module is doing it's job fine, and that some peculiar SP2 feature is the reason for the peculiar behaviour above.

if this is the case, and you do indeed find that -s $filename.zip of the above is non-zero, then i would suggest attempting to unzip it, in a separate script, using Archive::Zip. if the unzipping works, perl has done it's job properly, and you can check the SP2 experts for their knowledge on zip file problems.

alternately, if you have cygwin, you could check out the unzip tool to examine the archive, to do the same thing.
