[mod_python] Using gzip module with mod_gzip enabled apache breaks things ?

Any idea why using mod_gzip in apache makes gziping by gzip module hang apache 
server process ?
Currently I'm able compress content using mod_python nor mod_gzip (for static 
content), but not _both_ . :/

TIA for any ideas comments...
