12811	crash while trying to add way to relation	kennykb	team	"I was trying to add a way to an existing relation. The relation was huge, so I downloaded the relation and all members (using Download Object), and then the local area of the way. In the 'Edit relation' dialog, I got a crash while trying to set up to add ways to the relation.

Stack trace was:
