I don't have this problem because I use zlib to compress text but I
don't use zbuffer addon. The zlibapi is written by Oleg and contain
additional api to read/write directory data inside zip files.
Therefore if you only intend to use zlib, you don't need that addon
for working. For example the publish addon use zlib for writing pdf
files.
