Segmentation fault when using graph function (vtk 6.1, Qt5.3, Ubuntu) - c++

Question

Update: Debug info
I am working on a Qt 5.3 project and need to plot data in 2D and 3D coordinate systems. I've been looking into vtk 6.1 because it seems very powerful overall and I will also need to visualize image data at a later point. I have using Qvtkwidget smoothly with this example
Qvtkwidget example
#include "mainwindow.h"
#include <QApplication>
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
#include <vtkSmartPointer.h>
#include <vtkSphereSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkImageViewer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkInteractorStyleImage.h>
#include <vtkRenderer.h>
#include <vtkJPEGReader.h>
#include <QVTKWidget.h>
int main(int argc, char** argv)
{
QApplication app(argc, argv);
QVTKWidget widget;
widget.resize(256,256);
// Setup sphere
vtkSmartPointer<vtkSphereSource> sphereSource =
vtkSmartPointer<vtkSphereSource>::New();
sphereSource->Update();
vtkSmartPointer<vtkPolyDataMapper> sphereMapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
sphereMapper->SetInputConnection(sphereSource->GetOutputPort());
vtkSmartPointer<vtkActor> sphereActor =
vtkSmartPointer<vtkActor>::New();
sphereActor->SetMapper(sphereMapper);
// Setup window
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
// Setup renderer
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
renderWindow->AddRenderer(renderer);
renderer->AddActor(sphereActor);
renderer->ResetCamera();
widget.SetRenderWindow(renderWindow);
widget.show();
app.exec();
return EXIT_SUCCESS;
}
But when I tried to implement the graph example (/Examples/Charts/Cxx/QChartTable.cxx ), the program show Segmentation Fault errors.
#include <vtkAutoInit.h>

QVTKWidget *qvtkWidget = new QVTKWidget(&mainWindow);
// Set up my 2D world...
VTK_CREATE(vtkContextView, view); // This contains a chart object

// Create a table with some points in it...
VTK_CREATE(vtkTable, table);
VTK_CREATE(vtkFloatArray, arrX);

VTK_CREATE(vtkFloatArray, arrC);
arrC->SetName("Cosine");
table->AddColumn(arrC);
VTK_CREATE(vtkFloatArray, arrS);

table->AddColumn(arrS);
// Make a timer object - need to get some frame rates/render times
VTK_CREATE(vtkTimerLog, timer);
// Test charting with a few more points...
int numPoints = 29;
float inc = 7.0 / (numPoints-1);
table->SetNumberOfRows(numPoints);
for (int i = 0; i < numPoints; ++i)
{
table->SetValue(i, 0, i * inc);
table->SetValue(i, 1, cos(i * inc) + 0.0);
table->SetValue(i, 2, sin(i * inc) + 0.0);
}
// table->Update();
// Add multiple line plots, setting the colors etc
vtkSmartPointer<vtkChartXY> chart = vtkSmartPointer<vtkChartXY>::New();
view->GetScene()->AddItem(chart);
vtkPlot *line = chart->AddPlot(vtkChart::LINE);
line->SetInputData(table, 0, 1);
line->SetColor(255, 0, 0, 255);
line = chart->AddPlot(vtkChart::LINE);
line->SetInputData(table, 0, 2);
line->SetColor(0, 255, 0, 255);
line->SetWidth(2.0);
// Instantiate a vtkQtChart and use that too
/* vtkQtChart *qtChart = new vtkQtChart;
chart = qtChart->chart();
line = chart->AddPlot(vtkChart::LINE);
line->SetTable(table, 0, 1);
line->SetColor(255, 0, 0, 255);
line = chart->AddPlot(vtkChart::LINE);
line->SetTable(table, 0, 2);
line->SetColor(0, 255, 0, 255);
line->SetWidth(2.0);
*/
// Now lets try to add a table view
QWidget *widget = new QWidget(&mainWindow);
QHBoxLayout *layout = new QHBoxLayout(widget);
VTK_CREATE(vtkQtTableView, tableView);
tableView->SetSplitMultiComponentColumns(true);
tableView->AddRepresentationFromInput(table);
tableView->Update();
layout->addWidget(qvtkWidget, 2);
//layout->addWidget(qtChart, 2);
layout->addWidget(tableView->GetWidget());
mainWindow.setCentralWidget(widget);
// Now show the application and start the event loop
mainWindow.show();
return app.exec();
}
I have no idea how this error occurs.
I have recompiled VTK in debug mode and get more debug info. This is the backtrace for this program. In this screenshot show that problem could come form "this" pointer "this" should be vtkTextRenderer * but "this" point to null pointer. I think this could be a bug in VTK 6.1 but have no idea how to fix it.Please give me some suggestion. Thanks
I am newbie and still can not post picture so I upload it to this link

Answer 1

It is NOT a bug. The object vtkTextRenderer point to null bescause the Text Font module has NOT been implemented. It should been implemented using vtkRenderingFreeType.
Please try including this snippet in your code:
#include "vtkAutoInit.h"
VTK_MODULE_INIT(vtkRenderingFreeType);

Update Debug Info in first post.
