=begin
Some strange behavior of YAML in ruby 1.8.7 on simple string:

ruby-1.8.7-p330 :002 > require 'yaml'
=> true
ruby-1.8.7-p330 :003 > YAML::load("\n {\n}".to_yaml)
ArgumentError: syntax error on line 3, col 0: }' from /Users/sand/.rvm/rubies/ruby-1.8.7-p330/lib/ruby/1.8/yaml.rb:133:in load'
from /Users/sand/.rvm/rubies/ruby-1.8.7-p330/lib/ruby/1.8/yaml.rb:133:in `load'
from (irb):3

In ruby 1.9.2 seems to be all fine:

ruby-1.9.2-head :011 > require 'yaml'
=> true
ruby-1.9.2-head :012 > YAML::load("\n {\n}".to_yaml)
=> "\n {\n}"

Check this on Mac OS and FreeBSD:

Seems the bug is in escaping (to_yaml) :

ruby-1.9.2-head :002 > "\n {\n}".to_yaml
=> "--- "\n {\n\\n}"\n"

ruby-1.8.7-p330 :002 > "\n {\n}".to_yaml
=> "--- |-\n\n {\n}\n"

=end
