Does Apache seem to be compressing the file i.e. is Content-Encoding: gzip ? If it is not, which I suspect, mod_deflate did not compress the file. Judging from your configuration, there is no reason to believe that your zip files are treated any differently than pdf files.
What about the deflate log? Does that contain any indication of zip files being compressed whereas pdf files are not?
Did you try to unload or otherwise de-activate mod_deflate to see if that makes any difference?

Subject: [users@httpd] problem when using mod_deflate and zip files and IE6
Hi there,
When I use the following combination:
Apache 2.049
Linux (SuSe 9.1)
mod_deflate
and a zip file is served to a IE6 client, the file can not be used
anymore. (I get an error by win zip claiming that it is not a valid zip
archive)
I tried to suppress that mod_deflate by the following rule. This did
help with *.pdf files (which had the same problem), but not zip files.
Any help would be greatly appreciated.
Robert
