FileUtil.remove_entry_secure seems to be broken in my version (1.8.4).
I get:
undefined method fu_world_writable?' for FileUtils:Module /usr/lib/ruby/1.8/fileutils.rb:680:inremove_entry_secure’
#{RAILS_ROOT}/app/models/entry.rb:26:in process' ./script/../config/../app/controllers/image_manager_controller.rb:23:inprocess_upload’
Any ideas?
