LadonType arguments aren't handled properly in Python 3

[Piotr Szymankiewicz]

LadonType arguments raise ERemeotableException:

'dict_items' object does not support indexing

In soap11.py and soap.py we have:

if len(self.multi_ref_ids[self.cur_id_val].items()[0][1]):
 self.multi_ref_ids[self.cur_id_val] = self.multi_ref_ids[self.cur_id_val].items()[0][1]
else:
 self.multi_ref_ids[self.cur_id_val] = self.pickup_content

But in Python 3 items() returns a dict_items, not a list. Indexing raises an exception.
