Bug 96703

Version:           Unbekannt (using KDE 3.3.2 Level "a" , unofficial build of SUSE )
Compiler:          gcc version 3.3.3 (SuSE Linux)
OS:                Linux (i686) release 2.6.5-7.111.19-smp

error while parsing events in /home/heb/.kde/share/apps/korganizer/income - the timezone-list does not contain any timzones yet, so the timezones integrated in the events have to be read first

these changes led to 2 additional errors - MS uses the date 1601-01-01 as start-time for DTSTART and similiar properties. QDate can not accomadete these date (due to the Gregorian Calender, see documentation QDate). I guess it's OK to change the start year to 1753 in these cases. 
MS also introduces the additional property "X-MICROSOFT-CDO-TZID" (error "libkcal: Timezone::Timezone(): Unknown property: 54") - IMHO an error messsage in these cases is unecessary
