It assumes there is at least one transition.

            Transition t = fTraceDataModel.findTransition(netId,
                           fTraceDisplayModel.getCursorPosition()).next();
            g.drawString(fTraceDisplayModel.getValueFormatter(fCurrentNet).format(t),
                         1, fValueBaseline);

I only caused this with a VCD file I hand created. Most simulators will put at least one transition to set the initial state.
