Trac internal error while viewing timeline

[extesy]

How to Reproduce

While doing a GET operation on /timeline/, Trac issued an internal error.

I have changed filters in timeline view and pressed 'update'.

Request parameters:

{'wiki': u'on', 'changeset': u'on', 'from': u'12/02/08', 'update': u'Update', 'daysback': u'30', 'milestone': u'on'}
