12414	NPE in object history	naoliv	team	"I have imported this into JOSM:

http://127.0.0.1:8111/import?url=http://www.openstreetmap.org/api/0.6/changeset/36285819/download

Then zoomed in to the lower part where there is a big building and one smaller helipad.
Selected the helipad node and `Ctrl+h`

Then got this:
