NPE in RasterFiltersPlugin.layerAdded during MissingRoads initialization

[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?

What happens instead?

Null pointer but the plugin still continues to work.
