title: Ruby on Rails - Image translation missing: en.errors.messages.mini_magick_processing_error
body: <p>Have a Ruby on Rails app with carrierwave and imagemagick for image upload.  In my app, when I click to save record with the image upload, get an error "Image translation missing: en.errors.messages.mini_magick_processing_error".  Seeing this on a Heroku deploy.  I had this issue on both my local machine and on cloud9 Rails instance, which I resolved by manually running install of imagemagick.  Not sure how I would do that on heroku.</p>
