NPE with a network timeout when undeleting objects

[naoliv]

I had a network problem/timeout:

2017-02-22 09:47:39.363 GRAVE: org.openstreetmap.josm.io.OsmTransferException: Não foi possível conectar com o servidor OSM. Por favor, verifique sua conexão de internet.. Causa: java.net.SocketTimeoutException: Read timed out

Which is fine.
But the undelete plugin gave a NullPointerException:

Which I guess is not fine.
