The notable line here is in app.go. As of 579841097ddf2419a39c1a842b0bf66a146aa0ec (the current version), it is.

post = &posts[0]

There is currently no check to make certain that len(posts) > 0, and this causes a runtime error.

I too have this issue and can't work out how to fix it. I tried inserting a post manually into the database but I get the same error.

Any suggestions on how to fix?

Hrm, I originally had a bunch to pull in from a previous blog I wrote; I'll make sure that it'l work with 0 posts.
