mod_gzip problem

Problem with mod_gzip and Basic Auth?

[KennyJ]

I've just started using mod_gzip (1.3.26.1a) with Apache (1.3).
Everything is working fine apart from one directory which is password protected using basic auth.

Trying to access that directory gives a 403 error and "mod_gzip EMPTY FILE" error in the log.
I've actually set mod_gizip_on to 'No' for that directory but the problem still exists.

Any ideas on the reason/solution would be most appreciated...
