The Look and Feel (L&F) implementation that is used under Gnome (com.sun.java.swing.plaf.gtk.GTKLookAndFeel) has a bug, which causes a NullPointerException to be thrown at: weka.gui.PropertySheetPanel.addPropertyChangeListener(PropertySheetPanel.java:160) The workaround for this problem is to specify another default L&F when launching the java process by providing the commandline argument -Dswing.systemlaf=javax.swing.plaf.metal.MetalLookAndFeel Our next release 1.2.1 will have this fix included.
