Orchard homepage returned as "text/plain", browser shows text

When using CTRL-F5 to refresh my website, the page is returned as "text/plain" contenttype and the browser shows the html page instead of rendering it. If I do a simple refresh (probably uses some cached stuff) it returns as "text/html" showing the correct page.

So this only occurs the first 'hard' refresh.

Other pages then the homepage do not have this problem. I did not overwrite the 'document.cshtml' in the SafeMode theme.

Any ideas on where to look would be appreciated...
