Mime type is set to invalid/invalid

[tiagoovieira]

I have a couple of specs to test CSV uploads in the application, I create the file as following

let(:file) { fixture_file_upload('files/test.csv', 'text/csv') }

and I validate if the file is has a content_type of text/csv when I store the upload on the database. I upgraded carrierwave from 1.3 to 2.1, and that validation fails because the file has the content_type set to invalid/invalid

Is this a known issue?
