projman #4894 exception when start date is not a working day [resolved]

When the start date of the project is not a working day, the scheduling fails raising something like ValueError: Task t0 has no begin. In my case, the project had a constraint <constraint-date type='begin-after-date'>2008-03-01</constraint-date> with march 1st 2008 being a saturday.
