[Paraview] Plugin Crashing on PV 3.12 RC2

[Michael Jackson]

I have a custom reader plugin that I am trying to update for ParaView 3.12. Everything seems to compile OK and ParaView launches Ok. When I try to open one of my files I get the following:

ERROR: In /Users/Shared/Kitware-CVS/ParaView/ParaViewCore/ServerImplementation/vtkSIProxy.cxx, line 240
vtkSISourceProxy (0x121a07e60): Failed to create vtkH5VizFileReader. Aborting for debugging purposes.

Which is down in this section of the vtkSIProxy:

  if (className && className[0])
    {
    this->SetVTKClassName(className);
    vtkObjectBase* obj = this->Interpreter->NewInstance(className);
    if (!obj)
      {
      vtkErrorMacro("Failed to create " << className
        << ". Aborting for debugging purposes.");
      abort();
      }
    this->VTKObject.TakeReference(obj);
    }


In my "Gui XML" code I have this:
   <Reader name="H5VizFileReader"
          extensions="ddviz"
          file_description="ParaDis Vizualization File Reader">
  </Reader> 

and in the Server Manager XML I have this:
  <!-- ************************************************************ -->
    <!-- MultiBlock Reader For the dd3d Vizualization Files (.ddviz extension) -->
    <!-- ************************************************************ -->

I have cleaned the build directory a few times in the hopes that there was something weird with the configuration/compilation but that did not seem to help. I have not been keeping up with the changes going on with ParaView lately so this is all new to me. 

Any help would be appreciated.

Thanks
