[bug] nested dictionnary load works dump doesn't

[eugene@…]

import yaml
data=yaml.load("""
a: 1
b:
    ba: 1
    bb: 2
""")
yaml.dump(data)

[gives]

 'a: 1\nb: {ba: 1, bb: 2}\n'

pyYaml 3.0.3 - Python 2.4.3 - Windows XP

It's a correct output despite the fact that the style of the nested mapping is different.

If you want collections to be always serialized in a block style, try

>>> print yaml.dump(data, default_flow_style=False)
b:
  bb: 2
  ba: 1
a: 1
