HTTP headers showing up as text on page

[radixhound]

Hi, I have just set up a Rails site using the latest version of Radiant CMS (0.7.1). For some reason when I run the site off of LSWS, the headers are showing up as text at the top of the page. Sometimes all I get is the header and no page content...

This is the site up temporarily: http://s1.radixhound.com.

Can someone suggest if this is an LSWS issue? The headers don't show up when using Mongrel or Webrick.

This was set up using the basic virtual host template for Rails. I have 8 other Radiant sites on the same server with no issues (earlier versions of Radiant).

I'm not using any filters or rewrite rules (unless there are some filters as part of the virtual host template that I don't see)
