[Paraview] cluster: works with -np 1, crashes when runs in parallel :-(

[Sebastien Jourdain]

Hi Stephane,

Thanks for reporting it. In fact, that bug has been fixed in
ParaView/next and you can simply avoid it if you compile ParaView in
Release mode not in Debug.The problem come from an invalid test in an
assert().
I will make sure that the fix will be in 3.12.
