merge revision(s) 34919:

	* lib/yaml/rubytypes.rb (Exception.yaml_new): fix bug that causes
	  YAML serialization problem for Exception.
	  Exception#initialize doesn't use visible instance variable for
	  the exception message, so call the method with the message.
	  patched by Jingwen Owen Ou <jingweno AT gmail.com>.
