Also FWIW, I just configured mail.yml on my local development copy (using
smtp to my local server) and those aren't being sent out either.

If I send through the console using article.comments.create!, I can at
least see this in the log:

  User Load (0.000735)   SELECT * FROM users WHERE (notify_on_comments = 1)

And indeed the notifications then work.

I would do a bit more research but I'm not entirely sure where I should be
looking.  My naive guess is that this is somehow related to the new state
changing code, and perhaps the state of a piece of content changes
differently depending on whether it was created through the frontend or
the console.
