JOSM produces nodes with lat/lon 0.0 when I create a new OSM document

[avarab@…]

Under r1816 I can:

1. Open JoSM
2. Create a new document with C-n
3. Click around with the drawing tool to create new nodes

All of the nodes I'm creating will be added at lat/lon 0.0, furthermore I can't see them as I'm drawing them nor the lines between them (the only hint is the updated selection dialog).

I also can't scroll the mouse wheel to zoom in/out. Nor does the lat/lon display at the bottom of the screen update from 0.0/0.0. But I can grab the zoom adjuster and zoom out that way.

This also has nothing to do with my preferences since JOSM does the same thing once I move my preferences file elsewhere.

  </way>
