If it is a bug, it is not in the locale code.

>>> '%d' % float('224401250000.0000')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: int argument required

The documentation for the string formating operation doesn't
specify what happens when you convert a non-int with specifier
'%d'. In defense of your code, there's also no explicit
requirement to do that.
