redmine deploy on heroku cedar
===

I've been banging my head against the wall trying to deploy redmine 2.0.3 on heroku cedar.

I had lots of problems with deploying with sqlite gem so I removed all sqlite references from my Gemefile, deleted Gemfile.lock, ran bundle install, and happily pushed to heroku :)
I ran `heroku run rake db:migrate` and I browse to my app super extied  
 (http://blooming-river-8784.herokuapp.com/) and I see the following


    Application Error
    An error occurred in the application and your page could not be served. Please try again in a few moments.
    If you are the application owner, check your logs for details.

Okay I chek the logs and I see the following message:


    2012-07-12T01:34:47+00:00 heroku[run.1]: Starting process with command bundle exec rake db:migrate  
    2012-07-12T01:34:47+00:00 heroku[run.1]: State changed from starting to up

I googled this last line without sucess. so that's why I'm posting here hoping somebody will help :)
