You'll want to check what's in the log before this line. Try running `heroku logs -t` to get a continuous stream of log messages, then try going to your application in your browser.

Also, check to make sure you've run your migrations on the Heroku db with `heroku run rake db:migrate`; that's a pretty common issue with a freshly-deployed application...
