This causes a crash in python 3.2.2 and 3.2, but not in 2.7.2

C:\Python32>python
Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> datetime.datetime(1899,12,31).strftime("%y")

The crash happens with %y but not with %Y.
The crash happens with any year < 1900.
On 2.7.2 a ValueError is raised because strftime requires year >= 1900. This is what IMHO should happen (and would have saved me a lot of time)
