JOSM crashes when "aligning nodes" is used and only one node is focussed before

[aliponte]

Description of the error

I tried the new feature "Das Werkzeug Punkte in einer Gerade anordnen funktioniert jetzt auch bei Auswahl von nur einem Linienpunkt." (which means "Aligning nodes is now working even with a single node.") This feature has been introduced with version 4558.

I generated a line connecting two nodes. Then I generated a node not lying on this line. I focussed the single node and pressed key "l". Then JOSM crashed. This fatal error is reproduceable.
