egroupware_official/calendar/inc/class.calendar_ical.inc.php
Ralf Becker f37f8578cf - fixed calendar_ical::importVCal() to (again) return 0 on etag mis-match, as documented and return 412 Precondition Failed in that case 
- Disabling Schedule-Tag handling completly, as current implementation seems to create too much trouble with iCal under OS X or iOS, which send If-Schedule-Tag-Match condition event for major updates, not just changing own status or alarms
