Unexpected exception while fixing a problem

[naoliv]

What steps will reproduce the problem?

1. Clicked on validate to search for problems
2. Found a "No tags - Unconnected nodes without physical tags"
3. Selected (on the map area) the node and deleted it
4. Clicked on the problem (in the validation area) and clicked "Fix"
5. Got a "An unexpected exception ocurred"

What is the expected result?

JOSM should somehow verify that the node is already deleted and do nothing when clicking on "Fix"

What happens instead?

Gets an exception.

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