    Runtime criticals when closing an appointment editor with reminders
    
    There were printed two runtime warnings on close of an appointment
    editor when the appointment had filled any reminder. It was a side
    effect of a recent leak fix in an EAlarmList. The criticals were not
    critical, a NULL pointer had been used on a place where it should not.
