  Sorry.. I totally submitted that before writing anything...

  So what's happening is after doing a major overhaul of my site's code, and reimplementing scribd_fu with the latest version and Paperclip, whenever I go to save something or upload something to scribd, scribd_fu gets caught in an endless loop and saves a gazillion copies of the file to scribd.

  From my debugging, it seems like somehow scribd is triggering the after_save :upload_to_scribd callback on itself. No one else seems to be complaining about this bug though...

  Here's a sample stack trace from Eclipse:

  ipaper-test.rb contains:

  !/usr/bin/env ruby

  ENV['RAILS_ENV'] = 'development'
  require File.dirname(FILE) + '/config/boot'
  Rails.boot!
  require "#{RAILS_ROOT}/config/environment"

  r = SomeModel.first
  r.menu = File.open('/tmp/myfile.pdf')
  r.save

  Everything saves fine if I comment out:
  

  has_ipaper_and_uses 'Paperclip'

  Any idea what's going on? I'm totally stumped.. Everything used to work perfectly...

  FYI, I fixed this problem with the following patch.
