What version of ParaView are you using?  An early incarnation of 
vtkXMLPolyDataReader (and the corresponding writer) used the type name 
"float".  This version was never in a release of VTK so it was changed 
without backward compatibility.  If you edit the file and change it to 
"Float32" that error should go away.
