[vtkusers] allocating memory

I can't see the connection between those two lines - has one of the 
pointers been derived from the other one?

Building your own data structures is not that straight forward in vtk - 
you should know what you're doing or you might generate inconsistent 
data. It would be much easier to find your problem and help with a 
solution, if you posted more code.
