The directive "ReadmeName README" is supposed to print the file 'README' at the end of a directory listing. However, this doesn't work.
Apparently this changed in 1.3.6. Unless you have the mod_mime_magic module enabled (which is not the case by default), Apache cannot determine the type of a file named "README", and unless it can determine that its type is "text/plain", "text/html", or another "text" type, it will ignore it when generating directory indexes. Tests show that either enabling the mod_mime_magic module or changing the ReadmeName to something which can be guessed by mod_mime (like "README.txt") works, but the core should be assigning the DefaultType ot "text/plain" to it.
Thanks for the report. This is a mass bug update; since this release of Red Hat Linux is no longer supported, please either: a) try and reproduce the bug with a supported version of Red Hat Enterprise Linux or Fedora Core, and re-open this bug as appropriate after changing the Product field, or, b) if relevant, try and reproduce this bug using the current version of the upstream package, and report the bug upstream.
