Although I cannot guarantee this started with version 2.0.4, this was the first reported issue.
I have narrowed down the conflict to Jetpack activated, connected to WordPress.com, and the content being displayed in a single view (read: via single.php, page.php, etc.) This happens with every theme I have tested (my own and the Twenty series).
A work-around will be committed to the WordPress repository shortly, although I would much prefer a better solution.
