This error can be reproduced by using laod_and_zoom repeatedly (load, edit, delete layer(s), load, edit, delete layer(s), ...), for example when working on way check lists (in this case: ​http://www.gary68.de/osm/qa/c33/c33_bayern.htm).

Restarting josm helps to avoid this problem for the next ~3-7 tries

maybe real concurrent problem: see #3258
