Not a bug. Try yyyy (lower case) instead of YYYY.

According to http://babel.pocoo.org/en/latest/dates.html#date-fields:

y: Replaced by the year. Normally the length specifies the padding, but for two letters it also specifies the maximum length.
Y: Same as y but uses the ISO year-week calendar.

>>> import babel
>>> from babel.dates import format_date
>>> from datetime import datetime
>>> babel.__version__
'2.2.0'
>>> t = datetime(2016, 1, 2)
>>> format_date(t, 'd. MMMM yyyy', locale='en_US')
u'2. January 2016'
>>> format_date(t, 'd. MMMM yyyy', locale='de_DE')
u'2. Januar 2016'
>>> format_date(t, 'YYYY-ww', locale='en_US')
u'2016-01'
>>> format_date(t, 'YYYY-ww', locale='de_DE')
u'2015-53'

The documentation was improved by @ldwoolley in #450, so closing. Thanks 😃
