If I create a To Do item in KOrganizer that has a due date set, but no time, then export it to vcs format (File -> Export -> vCalendar), KOrganizer crashes on Q_ASSERT( dt.isValid() ) in VCalFormat::kDateTimeToISO. The "type" of the KDateTime variable, dt, is SpecType::Invalid.

To-Do items with no due date, or with a complete due date including the time of day, are exported without a problem.

The terminal output from the crash is:
