Mod_gzip will show the uncompressed page whenever the client who is visiting the page does not give a 'Accept-Encoding: gzip' header and Googlebot probably does not do that since I verified in my own logfiles it reads the uncompressed version. (ie. 31057 bytes against 4856 bytes compressed).
on a sidenote: inktomisearch does read the compressed pages (Yahoo Slurp bot)
