Can you verify that bad.gif begins with the string 'GIF'? Can it be viewed in
an app on the server itself? If the files are truly identical (one is a copy of
the other), just a diff will report that - does it?
Are you sure there are no leftover PerlHandler or SetHandler or similar
statements in httpd.conf?
I find it very odd to see actual perl source code in a served file, just because
mod_perl is configured. Was there anything unusual about the compilation of
Apache or mod_perl on this server?
