The ical validator at [1] states for the example ical file in attachment: "The time zone with the TZID 'Europe/Vienna' was not found." and suggests the resolution "to ensure the corresponding VTIMEZONE for TZID 'Europe/Vienna' is contained in the calendar." However, a VTIMEZONE component is present but it seems to be placed incorrectly. The RFC2445 [2] on ICalendar says on p. 61: "The "VTIMEZONE" calendar component cannot be nested within other calendar components." but the generated ical file of kronolith places VTIMEZONE within a VEVENT component. Putting the VTIMEZONE component after the VEVENT component by hand and revalidating this ical file again yields no more errors.
