[vtkusers] kernel32.dll error with VTK 5.0 and 5.0.2 in vtkInformationStringKey::Set

[Andres Barrera]

Hey Han,  ( ...yes,  I did get your message twice ;-)....  )

        Thank you very much for your help. Regarding to the error, I'll try 
modifying the original vtk implementation for vtkInformationStringValue, but 
I don't keep too much hope on it.... The construction looked weird to me 
too, but this class is being used by many people... Therefore somebody else 
should have fixed it before, but I didn't find anything on the users list... 
I addition, it is crashing 2 lines before it reaches 'v->Delete();'... 
Anyway, I will try anything anybody can think of, considering how frustrated 
I am... ;-)

        Thanks again


                              Andres
