[vtkusers] SetFilePrefix crashes application

[Ken Martin]

Hello Rene,

>From a quick look your code seems fine. My first guess would be that
somehow some old object files, headers or libraries are getting mixed
into the VTK 3.2 build (or execution in the case of shared libs) of
your application. Volume16Reader was pretty much unchanged between 2.3
and 3.2.
