[vtkusers] Valgrind complains when using vtkSmartPointer, depending on which object is created

[Liesbeth Vanherpe]

I´m running Ubuntu 13.04. The compiler version is "c++ (Ubuntu/Linaro
4.7.3-1ubuntu1) 4.7.3". The version of VTK is 5.8. I installed VTK through
"apt-get install libvtk5-dev".

Regards,

Liesbeth
