I remember having experienced similar problems when acces-
sing Apache via some broken WinGate proxy server and using
the "KeepAlive" feature.
Do you know whether there are proxies on your communication
way?

Either this script will produce chunked output, in which case
you would need to enable "dechunking" for mod_gzip, or it
doesn't, in which case the "dechunking" setting is irrelevant.
Look at your logfile (which should contain the mod_gzip status
value) which of both cases applies.
Or directly look at the created HTTP headers, using some trace
tool like

I have tried this (in the Apache config), but it didn't change
anything.

I switched off KeepAlive, and it helped, but didn't eliminate
the problem totally. But I experience this problem very rare-
ly, since the aforementioned proxy is out of the game now.

Greetings,
