I get a 500 when post_to_page? is true.

Here's the console
http://gist.github.com/raw/178897/c5c1f45e4e0e1e9858ea6126854c3faa373e56c2/gistfile1.txt

This is my settings.yaml
http://gist.github.com/178904

And this is the log
http://gist.github.com/178905

If I set post_to_page? to false, attempt to post an empty comment, set it back to true and then fill in the comment, it works fine. Until I try to post a new comment. Then it's a 500 again.
