Rails 4.2.1 has suitable `config_for` method http://apidock.com/rails/v4.2.1/Rails/Application/config_for + secrets.yml + rails .env. So this gem has to be dead.

I've fix this with the following patch: ```ruby CarrierWave::Mounter.prepend(Module.new do def remove_previous(before = nil, after = nil) before &&= Array.new(before).map(&:to_s) after &&= Array.new(after).map(&:to_s) super(before, after) end end) ```

Sorry, but I cant reproduce the issue

@mib32 You should capture `faraday.headers` also, especially `content-type` header, this will help a lot.
