No, unfortunately still unsolved. The small ascii vtk file in my respond to Steve Pieper should work for demonstrating the problem.
Note: A ‘number sign’ or ‘hash’ should be added as first character to the first line ‘vtk DataFile Version 4.2’ (/# vtk DataFile Version 4.2), which probably is just a comment for the vtk reader (I tried to ‘escape’ the symbol, but it seemed that it did not work).
