Yes, see this bug <http://quality.runrev.com/qacenter/show_bug.cgi?id=5088>
It happens if you add or remove files from a zip that was not
originally created in Revolution.

You need to specify a file name, open that file as a zip archive ready
for updating, add new files to it, then close the zip file. Check the
docs for the following commands:
    revZipOpenArchive
    revZipAddItemWithFile
    revZipCloseArchive

In theory, it works for any zip file, but at the moment, you can only
edit zip files created in Rev. Unfortunately, this makes the zip
library almost useless, since the only way to test whether a zip file
will work is to risk corrupting it permanently and losing any data in
it.
