Hello,

I have a ParaView master compiled on GNU/Linux with VTK_DEBUG_LEAKS=ON. If I set the environment variable VTK_DEBUG_LEAKS_TRACE_CLASS to "vtkInformationVector":

export VTK_DEBUG_LEAKS_TRACE_CLASSES="vtkInformationVector"

then, simply creating a wavelet or a poly-line source makes ParaView crash with a double free of corruption (when I hit the Apply button). Here is the Loguru trace:
