As near as I can tell, this is a problem with Django / Jython
compatibility and not my code... if I'm wrong feel free to slap my
wrist...
A form was created with the following field:
start_date = forms.DateTimeField(required=True,
widget=forms.DateTimeInput({'class': 'datetime'}))
The following POST data was passed:
start_date u'11/03/2012 00:00:00'
The following traceback was received when I check for form.is_valid() in
the view:

At 441, format = '%Y-%m-%d %H:%M:%S.%f'
The %f formatting character was introduced in Python 2.6, but it is not
supported in Jython, even in the 2.7 alphas.

I remember this code working fine in Django 1.4.1, but I cannot seem to
find a commit that would have broken it during the timeframe between the
1.4.1 and 1.4.2 releases.
