[7.0][scheduler_error_mailer] Error when field is of type date

When you base the configurator in a date field, it fails with this error:

2014-04-28 10:38:39,793 32648 ERROR grupoesoc openerp.addons.base.ir.ir_cron: Call of self.pool.get('super.calendar.configurator').generate_calendar_records(cr, uid, *([], {})) failed in Job 10
Traceback (most recent call last):

    (data_string, format))
ValueError: time data '2014-02-27' does not match format '%Y-%m-%d %H:%M:%S'

It should detect if the field is of type date to avoid this exception, or at least not allow the user to use a date field to schedule.
