Do Not Panic.
Like any good search engine, the googlebot periodically asks for pages using the "wrong" hostname (with or without www., whichever form you don't use). Assuming you redirect these requests to the right form, it will show up in logs as a 301 just like any other redirect.
HTTPS to/from HTTP is another perfectly reasonable possibility, assuming you've got a redirect in place.

Well. I have no idea what that's all about, but if I manually request my own site with https (which I don't use), the browser simply hangs. Tried two different browsers to make sure. Wonder what it's doing? Anyone know what's supposed to happen when you request the wrong protocol?
