5634	junctionchecking plugin crashes when deleting a layer	rickmastfan67	joerg	"Steps to reproduce:
1. Start a fresh session in JOSM.
2. Download anything from OSM (example: download relation 417224).
3. Once the relation (or anything else you downloaded) is loaded in JOSM, on the right in the layers area, delete your only ""layer"", which should be called ""Data Layer 1"".
4. junctionchecking crashes.
NOTE: This happens by itself or with other plugins installed.
