Error trying to resize the original file with Ghostscript

[llollox]

That's my picture.rb model.

class Picture < ActiveRecord::Base
belongs_to :picturable, polymorphic: true

  has_attached_file :photo, #, :storage => :dropbox,
  :styles => { :thumb => ["100x100>", :jpg], :scaled => ["300x300#", :jpg], :medium => ["600x400>", :jpg], :original => ["1200x800>", :jpg]},

  :processors => lambda { |a|
   if a.is_pdf?
     [:ghostscript, :thumbnail]
   else
     [:thumbnail]
   end
  },

  :convert_options => { :all => '-density 300 -quality 100' }

  validates_attachment_size :photo, :less_than => 5.megabytes
  validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png','application/pdf','image/gif']

  def is_pdf?
     ["application/pdf"].include?(self.photo_content_type) 
  end

end

Trying to upload a pdf file I give the following error, but if I don't assign a style for the original file (es replacing :big instead of :original) everything works correctly!
