The one thing you're not saying is under what Catalyst is running when  
it's producing that. Are you running FastCGI? Mod_perl? Stand-alone  
development server?

If it happens in all of those then the bug is probably in your code  
(though after your debugging statements). If the insertion is indeed  
happening outside that pretty much just leaves the Web server, or  
perhaps a proxy. Wild stab in the dark: do you happen to have SSI  
turned on?
