The same program and version, although it reports modification date of 
14 Feb 2005.
I've just now verified that emacs 23.1 doesn't exhibit this bug, with 
the same unzip.exe, init.el, etc.

If you compare the sources of archive-zip-extract in arc-mode.el between 
versions 23.1 and 23.2, the addition of (shell-quote-argument name) for 
"unzip" is the main change. It seems that this argument is quoted again 
by 'call-process, see attached callstack.txt and procmon.png.
