ara, try this:

% irb
irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> sym = :"a symbol"
=> :"a symbol"
irb(main):003:0> sym == sym
=> true
irb(main):004:0> sym == YAML.load(YAML.dump(sym))
=> false
irb(main):005:0> sym
=> :"a symbol"
irb(main):006:0> YAML.load(YAML.dump(sym))
=> :"\"a symbol\""
irb(main):007:0> VERSION
=> "1.8.4"

Looks like a bug to me.
