[Paraview] some tables cannot be located using paraview.simple python api

[Laurent Vanboquestal]

I found the problem ... In fact, the th z table is refering to Velocity in
my case)... and the for the non-working cases, range are between [0, 0]
And it seems to give problems as this table is used by Glyph2 ....
