2672	[PATCH] java.lang.NullPointerException at org.openstreetmap.josm.plugins.measurement.MeasurementLayer.calcDistance(MeasurementLayer.java:158)	phobie	dmuecke	" * OS: Debian/sid
 * JOSM: 1621
 * Java: 1.6.0_13-b03 

IMHO I did nothing special.[[BR]]
Measurement plugin was installed but not activated in the GUI.[[BR]]
I am unable to reproduce this bug.
