I have updated to 1.207 snapshot and copied my windows setup over to a linux
box. I decided to try the system using winstone rather then the tomcat setup I
was using but when I try to change my main hudson config it fails to save so I
had to make the changes directly to the files. I do not get any error messages.

When however I try to save a job configuration I get the following error. The
other change I have made is to install the ci-game plugin

Status Code: 500
