I'm trying to use aeditor with the gem version of the Iterator library 
and am getting the following error

/usr/local/lib/ruby/site_ruby/1.8/aeditor/lexer.rb:4: [BUG] Segmentation 
fault
ruby 1.8.0 (2003-08-04) [i686-linux]

this can be fixed by either

1: uninstalling the iterator gem and installing it from a tar.gz

2: changing buffer.rb to replace the line
require 'iterator'

with

require 'rubygems'
require_gem 'iterator'

so the problem only manifests when using the gem version of iterator 
through the stub file.

this is using
aeditor version 1.3
rubygems version 0.7
iterator version 0.8
