[Paraview] error using new reader

[John Biddiscombe (CSCS)]

Could anyone please point me to the way to solve this problem. Paraview 
gives me this error before quitting and I'm not sure if I'm missing a 
member in the reader, or some definition in one of the pvsm or xml 
files. any clues welcome.

thanks

JB
