Seth,
It's actually very easy to reproduce this issue - from a browser request
http://musikandfilm.com/?a=b and you will see it. There are a couple of low
level tools that expose some possible issues.
If you email me directly I can talk about this in more detail. Try peter
underscore booth at me dot com.
