It occurs when vtkAtom is printed, not vtkMolecule, so PrintSelf isn't
involved.  When a special type like vtkAtom is printed, the "<<"
operator is used, if it is defined for the class.

For example, vtkVariant.h has the following line:

VTK_COMMON_EXPORT ostream& operator << ( ostream& os, const vtkVariant& val );

Of course, the absence of that operator should not cause a wrapped
special type to crash, so I'm not quite sure what is going on.
