crash on lit streets mappaint style

[malenki]

What steps will reproduce the problem?

1. start JOSM with a blank ~/.josm directory
2. add the mappaint style "Lit" (in German "Straßenbeleuchtung") by cmuelle8
3. click "OK"

What is the expected result?

JOSM uses lists that style in the Mappaint styles box

What happens instead?

This crash

This seems to be a regression introduced after r8090 which works fine. I experienced this error first when running r8100 and tracked it down to this entry in the preferences.xml:

    <map>
      <tag key='title' value='Straßenbeleuchtung'/>
      <tag key='active' value='false'/>
      <tag key='url' value='http://josm.openstreetmap.de/josmfile?page=Styles/Lit&amp;style'/>
    </map>
