SystemExit (exit): attachment_fu 500 error

In production mode, my app is returning a 500 error having to do with attachment_fu in my comments model. Here is my original model that worked in development mode:

<---- Original Comment Model (not working) ------------------>

class ApplicantComment < ActiveRecord::Base   belongs_to :applicant

  has_attachment :storage => :file_system, :path_prefix => "public/ file_attachments/"

  def partitioned_path(*args)     ("%04d" % applicant_id).scan(/..../) + args   end end <------->

The reason I know it's because of attachment_fu is because the only way I can get the page to load is by stripping out everything except the 'belongs_to', like this:

<---- Modified Comment Model with Attachment (works) ------------------

class ApplicantComment < ActiveRecord::Base   belongs_to :applicant end <------->

Here's my log. Could it have to do with ImageScience even though the files are not images?

UPDATE:

It turned out to be a problem with the server's installation of Image science. I did not have the image processor defined, so it was wanting to use Image Science. The server has Rmagick, so I updated my model:

class ApplicantComment < ActiveRecord::Base   belongs_to :applicant

  has_attachment :content_type => :image,                  :processor => :Rmagick,                  :storage => :file_system,                  :path_prefix => "public/file_attachments/"

  def partitioned_path(*args)     ("%04d" % applicant_id).scan(/..../) + args   end end
