The Mac OS/X problem with action=upload and zip files only
is most likely because of a bug in the ZipReader (gzinflate or gzopen)
or some problem with the is_uploaded_file() handling with zip files.
It fails with an simple "Fatal PhpWiki Error
No uploaded file to upload?"
The temp. workaround is to use action=loadfile which doesn't restore all
versions, only the latest version.
Can some experienced developer with Mac OS X (Micki has php 4.3.2)
debug this? (Carsten?)
I would say that we should release 1.3.8 even with this known bug,
which existed before. It just should prominently noted.
