NPE when selecting a zero-node way

[Cobra]

What steps will reproduce the problem?

1. find a way without nodes (e.g. download an earlier version of a deleted way)
2. select it (via search)
3. watch the measurement plugin crash

What is the expected result?
nothing. maybe some NaN instead of numbers.

What happens instead?
said NPE.
