ways without nodes (Undelete Plugin)

[Nakaner]

What steps will reproduce the problem?

1. Download Dessau-Ziebigk, Germany.
2. Create a second layer and activate the second layer.
3. Run the Undelete-Plugin File -> Undelete Object for all objects that were deleted in changeset 13877017
4. First do this with all nodes, afterwards with all ways that were deleted.
5. Try to upload. The bug message will occure.

What is the expected result?

The deleted ways and nodes should have been restored. I wanted to upload them.

What happens instead?

The bug message came. JOSM did not crash.

Please provide any additional information below. Attach a screenshot if
possible.
