    I went through the following issue with the latest version
    of `babel <https://pypi.python.org/pypi/Babel>`_ (2.0).
    It happens when I try to generate the documentation for this module.
    It gave me the following exception::

          File "c:\python34_x64\lib\site-packages\sphinx\__init__.py", line 51, in main
            sys.exit(build_main(argv))
          File "c:\python34_x64\lib\site-packages\sphinx\__init__.py", line 61, in build_main
            from sphinx import cmdline
          File "c:\python34_x64\lib\site-packages\sphinx\cmdline.py", line 23, in <module>
            from sphinx.application import Sphinx
          File "c:\python34_x64\lib\site-packages\sphinx\application.py", line 37, in <module>
            from sphinx.builders import BUILTIN_BUILDERS
          File "c:\python34_x64\lib\site-packages\sphinx\builders\__init__.py", line 23, in <module>
            from sphinx.util import i18n, path_stabilize
          File "c:\python34_x64\lib\site-packages\sphinx\util\i18n.py", line 15, in <module>
            from babel.messages.pofile import read_po
          File "c:\python34_x64\lib\site-packages\babel\messages\__init__.py", line 12, in <module>
            from babel.messages.catalog import *
          File "c:\python34_x64\lib\site-packages\babel\messages\catalog.py", line 23, in <module>
            from babel.dates import format_datetime
          File "c:\python34_x64\lib\site-packages\babel\dates.py", line 28, in <module>
            from babel.util import UTC, LOCALTZ
          File "c:\python34_x64\lib\site-packages\babel\util.py", line 278, in <module>
            from babel import localtime
          File "c:\python34_x64\lib\site-packages\babel\localtime\__init__.py", line 21, in <module>
            from babel.localtime._win32 import _get_localzone
          File "c:\python34_x64\lib\site-packages\babel\localtime\_win32.py", line 18, in <module>
            tz_names = get_global('windows_zone_mapping')
          File "c:\python34_x64\lib\site-packages\babel\core.py", line 58, in get_global
            _global_data = pickle.load(fileobj)
        TypeError: an integer is required (got type str)

    The exception disappeared after I reverted to babel 1.3.
