Certainly. I should mention, I am using a pre-compiled version of Paraview 4.1 bundled with Salome (Ubuntu package).
Here it is (using pReader->SetForceOutputTypeToMultiBlock(1)): ERROR: In /misc/dn47/SALOME/PRODUCTS/7x/opt/Ubuntu.13.10.64/7.4.0/tmp/ParaView-4.1.0_SRC/ParaViewCore/VTKExtensions/Default/vtkXMLCollectionReader.cxx, line 316 vtkPVDReader (0x6559e0): Error creating "vtkXMLMultiBlockDataReader" using vtkPVInstantiator.
