10834	IllegalArgumentException when tracing buildings with Tracer2 plugin	hpduwe@…	team	"==== What steps will reproduce the problem?
1. Tracer begin
2. Buildings are not drawn
3. another building can be drawn however 

EDIT: from #10871:
1. Use the plugin tracer2
2. Use nrw alk as data source
3. Sometimes (when you try to draw the outline of the building with the plugin) the plugin crashes. At this time a non existent outline in osm should be drawn which borders to an existent osm outline/building.

==== What is the expected result?

==== What happens instead?

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