A mix of plugins along with the new Missing Roads plugin produces a null pointer exception -- The bug/ticket may or may not be yours.

[anonymous]

What steps will reproduce the problem?

1. Start JOSM with the list of plugins.
2. Used OSM to remote control an area with ​http://www.openstreetmap.org/edit?editor=remote&way=32136087#map=17/32.16245/-110.92363
3. Dos window reports

4. I keep the Plugin during the "Do you want to remove the plugin?" question.
5. The same remote control URL produces

What is the expected result?
