[vtkusers] Getting debug errors when deleting objects !!!

[Dominik Szczerba]

You dont get an error because the system releases the memory on exit() itself 
and it seems to do better than you, who delete them in a wrong order. The 
easiest solution is to use smart pointers - or to analyze what depends on 
what.
