Fail to upgrade and precompile assets

Hi,

I just upgraded my Gitlab from 7.1 to 7.7 and when came the assets precompile command it failed to find chart-lib.min:

-> bundle exec rake assets:clean assets:precompile
rake aborted!
Sprockets::FileNotFound: couldn't find file 'chart-lib.min'
  (in /home/git/gitlab/app/assets/javascripts/application.js.coffee:25)

Someone see why?
