[Matthias Klose]

Package: src:ruby-rails-assets-favico.js
Version: 0.3.9~dfsg-3

Even after fixing #821399, the autopkg tests still fail:

Bundle complete! 13 Gemfile dependencies, 54 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
+ bundle exec rake assets:precompile
rake aborted!
Sprockets::FileNotFound: couldn't find file 'favico.js' with type
