Rails - Sep 2009 - Problem accessing paperclip file attributes in a callback (observer)

I''m having trouble accessing paperclip file attributes in an
after_destroy callback on my attachment model.  I can''t seem to access
the paperclip-managed attributes but I can access non-paperclip
attributes.  Here''s an example:

class AttachmentObserver < ActiveRecord::Observer
  def after_destroy(attachment)
    attachment.logger.info "Deleted #{attachment.user.username} :: #
{attachment.name}"
  end
end

The log message will say "Deleted Jsmith :: ".  No attachment name
though.  Thanks for any help.

Here''s a gist if you need it.
