When I'm signed into my wpcom test site I'm seeing self-hosted sites connected to jetpack in my wpcom site list. I can also add that self-hosted site via the add sites, and still connect it to Jetpack. The result is I have an entry for the site under wpcom and self-hosted sections.
If I choose the self-hosted entry, and try replying to a comment via the Notifications or Me tab, I see the following error. The cause seems to be that the self-hosted version is making the call to the REST API passing a blog ID of 0.
