Subject: YAML.load({[]=>""}.to_yaml)

I found that current YAML doesn't round trip {[]=>""}.

% ./ruby -v -ryaml -e 'p YAML.load({[]=>""}.to_yaml)'
ruby 1.9.0 (2006-01-10) [i686-linux]
/home/akr/ruby/lib/ruby/1.9/yaml.rb:133:in `load': syntax error on line 2, col 1: `: ""' (ArgumentError)
        from /home/akr/ruby/lib/ruby/1.9/yaml.rb:133:in `load'
        from -e:1

ruby-1.8.2 works well.

% ruby-1.8.2 -v -ryaml -e 'p YAML.load({[]=>""}.to_yaml)' 
ruby 1.8.2 (2004-12-25) [i686-linux]
{[]=>""}
