If you use sidebars for navigation the Links section of a page ends up looking like:

Links: blog/posts blog/sidebar sidebar

instead of what I would expect:

Links: blog/posts blog index

I'm not sure what the bug actually is, or if there even is one, this just seems odd.

If you have a page named "sidebar" and a page named "blog/sidebar", and they each link to a page, then of course they will show up in that page's list of links. The index page does not link to the page, so is not listed, which is appropriate. Notabug --Joey
