Your problem is that you've not configured the content type header correctly on your server. Here's the response to the HTTP request for cache.manifest:
HTTP/1.1 200 OK
Date: Tue, 08 May 2012 09:33:41 GMT
Server: Apache
Last-Modified: Tue, 08 May 2012 05:07:32 GMT
Etag: "733106-652-4bf7f5d3692a8"
Accept-Ranges: bytes
Content-Length: 1618
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Content-Type: text/plain
See that last line? It should be text/cache-manifest. Change the content type in your server configuration. For Apache you can add this line to the server config or in an .htaccess file:
AddType text/cache-manifest appcache manifest
