2015-08-17 Issue with module babel¶

I went through the following issue with the latest version of 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
  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

    from sphinx.builders import BUILTIN_BUILDERS

  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.
