Error in db:migrate_plugins

[bsides]

I'm getting the following error after running rake db:migrate_plugins RAILS_ENV=production. I don't know if it's a problem related to redmine_digest or not but if you could help I'd really appreciate it. My server is a Ubuntu 11 VPS with LAMP and Redmine already running (http://pro.bsides.co).

Thank you!

I have the same problem

My Server is a Debian Linux 6.0...redmine works well without this plugin
