Redmine

I've checked out trunk from svn and am running into an error when trying to start the application (from the web, or by script/console):

/home/codexed/.gem/ruby/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:426:in `load_missing_constant': Expected /home/codexed/redmine/app/models/user.rb to define User (LoadError)
        from /home/codexed/.gem/ruby/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:80:in `const_missing'

My app/models/user.rb file is not modified and it's clearing defining the User class near the top of the file, so I'm not really sure what's going on here... any suggestions?
