NPE at PropertiesDialog.selectionChanged when selecting object from geojson file

[ibemerson@…]

What steps will reproduce the problem?

1. load geojson file
2. click on an object

What is the expected result?

The selected object's tags and info should display in the boxes on the right side of screen.

What happens instead?

An error box instantly pops up. Every Time. If error is ignored, JOSM does not display any existing tags for the selected object. All the boxes on the right of screen act as if no object is selected. If I click "Edit" then click "Edit tags" the box that pops up lists all the objects tags and I can edit them there normally.

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

The errors began right after updating to latest version. The geojson files worked fine on previous versions.
