Redmine

Hello!
I try to upgrade my redmine installation on an Ubuntu 14.04. I checked out the master with git. After this i ran "bundle exec rake db:migrate RAILS_ENV=production" like it is described here. Then I got the following error:

20150113194759 CreateEmailAddresses: migrating ===========================
-- create_table(:email_addresses)
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
