[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

[Richard GRENON]

Hi Dave and Burlen

Another Test loading state for a Tecplot file that contains two zones works!

- Read two zones Tecplot File
- Extract Block 1
  | Extract subset 1 from Block 1
    - Color Subset 1
- Extract Block 2
  | Extract subset 2 from Block 2
    - Color Subset 2

Another Test loading state for a Tecplot file that contains only one 
zone crashes PV.
- Read single zone Tecplot File
- Extract subset
- Color Subset

A final Test loading state for a Tecplot file that contains only one 
zone and using "Group datasets" filter works!
- Read single zone Tecplot File
- Group datasets
- Extract subset
- Color Subset

So the problem happens only when reading single zone Tecplot files. The 
work around is always to use the "Group datasets" filter after reading, 
even if there is only one file! No problem occurs when reading a 
multi-zone Tecplot file.

Best regards.
