 I'm unclear if this is a bug specific to the wordpress.com deployment or
 whether it's a general issue. I don't have a non wordpress.com blog which
 responds to both http and https to test this on, and I've not investigated
 the code for this.

 In short the issue is this:

 Wordpress feed entries have their guid field calculated based on the
 protocol. i.e. a guid is something like
 http/https://drmaciver.wordpress.com?p=blah. If I request
 https://drmaciver.wordpress.com/feed I'll get https guids, if I request
 http://drmaciver.wordpress.com/feed I'll get http guids.

 The problem is that this is cached for a period of time, and the cache key
 ignores the protocol. This means that if I request
 https://drmaciver.wordpress.com/feed, get https guids, and then
 immediately request http://drmaciver.wordpress.com/feed then I will get
 https guids in the http feed. This will continue to be the case until the
 cache expires and the new feed is calculated with the appropriate guids.
