khal: Offset-error

I am syncing calendars from iCloud and with loads of events I get the following error:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/khal/khalendar/khalendar.py", line 189, in _update_vevent
    ignore_invalid_items=True)
  File "/usr/lib/python2.7/site-packages/khal/khalendar/backend.py", line 269, in update
    ical = icalendar.Event.from_ical(vevent)
  File "/usr/lib/python2.7/site-packages/icalendar/cal.py", line 350, in from_ical
    vals = factory(factory.from_ical(vals))
  File "/usr/lib/python2.7/site-packages/icalendar/prop.py", line 818, in from_ical
    'Offset must be less than 24 hours, was %s' % ical)
ValueError: Offset must be less than 24 hours, was +5328
During `update_vevent` we failed to parse vcard work/someevent.ics with error
"Offset must be less than 24 hours, was +5328",
this means, that event is not available in khal.

For one: the event is not in work/something.ics but in home/something.ics which is strange. And then there is the content of the .ics which has an Offset of +5328 in one line:
