Premature end of script headers

Hello, I'm having the weirdest problem. I'm trying to install PHP as a CGI program using SuExec and FastCGI but I keep on getting a "Premature end of script headers: php" error in my Apache error_log. I got it working when I set up PHP to run as a CGI program when there's no virtual hosts, but as soon as I create a virtual host I get the end of script headers error. I'm trying to get PHP working as a CGI program before attempting to get it to run via FastCGI. Since I'm able to make it work without virtual hosts I'm assuming that my configuration is correct and that the problem lies in the virtual host itself. Here's the virtual host as it stands. <VirtualHost *:80> ServerName hostname DocumentRoot /home/user/htdocs DirectoryIndex index.php index.html ErrorLog logs/error_log SuExecUserGroup user users </VirtualHost> Does anyone know of a way around this problem? Thanks, Kevin
