+Fixed a bug where :mod:`calendar` could raise an uncaught :exc:`ValueError` on import when falling back from :data:`calendar.standalone_month_name`/:data:`calendar.standalone_month_abbr` to :data:`calendar.month_name`/:data:`calendar.month_abbr`, on platforms where ``strftime()`` accepts ``%OB``/``%Ob`` when a name object is constructed but rejects them once the value is actually formatted (e.g. under Wine).
