19432	Split way: AIOOB: Problem with member check with duplicate members	skyper	GerdP	"==== What steps will reproduce the problem?
1. Have some new route relations, see [attachment:josm_split_way_exception_example.osm.bz2]
1. Select a middle node of way with membership (1523436358)
1. Split way

==== What is the expected result?
Either the dialog asking to download members comes up or the way is splitted

==== What happens instead?
AIOOB

==== Please provide any additional information below. Attach a screenshot if possible.
The problem seems to be a relation where the way is multiple times present in the relation.
If I choose to give the long part (5 nodes) a new id it works but this is only an option in expert mode.
