[Paraview] Warning reading ascii data

I don't profess to be an expert on the VTK file reader, but looking at the source code leads me to believe that the number of entries in one of the arrays in your file does not match the number identified above it.  Specifically, there are probably less entries than declared.  For example, in the example below perhaps there are less than 3309568  point coordinates listed.  Without seeing the whole file I cannot be sure.

I know paraview for nearly one week and I'm trying to make the best use of it.
I'm working on 2Dpropagating fronts and it seems that paraview can be very usefull for me. I already succeeded to visualize the 2D results but that is not my last project. I want to have a 3D pislay of it by putting the rounded values in the third dimension. It works nearly perfect. I can see my results as I want (display points and color by elevation) but I always have a warning message :

Generic Warning: In /home/Arbaal/paraview/ParaView3/VTK/IO/vtkDataReader.cxx, line 1381
Error reading ascii data!

That is not a big probleme when I just look at one file at a time, but I'm looking to the temporal evolution of the fronts, and the warning appears for each display. What is my problem? Or how could I do to don't show this warning?

My matrix are large (smallest should be around 64*512 in 2D, I put 100points for my scalars) and my .vtk file looks like

# vtk DataFile Version 2.0
DIMENSIONS 512 64 101
POINTS 3309568 float
0.000000 0.000000 20.275200

0.000000 6.000000 20.275200
0.000000 7.000000 20.275200

My paraview version is the actual on CVS (3.5.0) and I work on Ubuntu (Unix-like)

If you have any idea on what is my problem, I'll be happy to hear it.


PS : I hope I didn't send this mail two times
