I've attached a patch for pyvtk/common.py that "fixes" this problem.
However, this is unlikely to work when you actually read the data file
because it will use ints to specify the data in the VTK file.  I
suggest that you specify the data in the form of floats or doubles.
So convert your arrays to double/float arrays and everything should
work.
