Summary:                    Crash in vtkChartXY::RemovePlot
Description: 
The following call to RemovePlotInstance crashes because of a NULL pointer
dereference in vtkChartXY::RemovePlot():996

#include <vtkChartXY.h>
#include <vtkContextScene.h>
#include <vtkContextView.h>
#include <vtkPlotLine.h>

int main()
{
   vtkChartXY *chart = vtkChartXY::New();
   vtkPlot *line = vtkPlotLine::New();
   chart->AddPlot(line);
   chart->RemovePlotInstance(line);
   line->Delete();
   chart->Delete();
   return EXIT_SUCCESS;
}

I'm attaching a patch that fixes it for me (based on tag v5.8.0).
