TypeError: can't compare datetime.datetime to NoneType

How to Reproduce

While doing a POST operation on /milestone/milestone4, Trac issued an internal error.

(please provide additional details here) I edited the other milestones on the default project, and they worked fine. I tried re applying the update on this milestone and it worked fine.

The form post is detailed below for a clean new project.

Request parameters:

{'__FORM_TOKEN': u'37ba096de8aa6b8041c5ab10',
 'action': u'edit',
 'completed': u'on',
 'description': u'Parallel running starts at 9:00am on Tuesday 10th April and completes on the Friday.',
 'duedate': u'04/13/07',
 'id': u'milestone4',
 'name': u'Parallel Running'}

[Christian Boos]

The current corresponding code looks rather like:

            if milestone.completed and milestone.completed > datetime.now(utc):

so I think this is no longer an issue with latest trunk.
