NPE at plugin czechaddress

[bilbo]

Loaded some data from OSM, then I picked two ways, combined them, solved conflicts in the dialog and ... I got this exception - then clicking anywhere in the map in attempt to select anything mean another exception (the same one). Note that I was not actively using the czechaddress plugin at the time I got this, I had the panel turned off and I have not used it in this JOSM session.

Somehow your dataset contained an "zero nodes" way. The question is whether we fix the exception or the place where you created that way. Can you reproduce this issue?
