I just ran into something like this, using Radiant 0.6.7, SnS 0.4, and - 
like Arik had been - thin, proxied through Apache.

Turns out it's not an Apache thing at all: it's thin, complaining that 
@response['Last-Modified'] isn't a string.  And it's got a point!

Suggestion for text_asset_site_controller:

    # set the last modified date based on updated_at time for the asset
    # we can do this as long as there is no dynamic content in the assets
-        response.headers['Last-Modified'] = 
@text_asset.effectively_updated_at
+        response.headers['Last-Modified'] = 
@text_asset.effectively_updated_at.to_s
          response.body = @text_asset.render
