NullPointerException when failing to connect to OSM API Server

[david@…]

After loading a TCX file from the garmin training center (with the tcx-support plugin) I tried to download the osm data. so I zoomed out a bit, and hit the download button, and accept the default coordinates. An error message pops up: "Der Aufbau der Verbindung zum OSM-Server ist fehlgeschlagen. ..." press OK, error pops up again, press OK, the default dialog for unexpected errors comes and shows this trace:

The error seems to be unrelated to the tcx-support, I can reproduce it without loading a TCX file first.

Actually, this seems to have been caused by an empty osm-server.orl setting. No idea how that happened, but it was empty and after setting it (again?) to " http://www.openstreetmap.org/api" I could download OSM data again.
