[vtk-developers] vtkContainer.cxx checkin last night

[Blezek, Daniel J (Research)]

Andy,

  Some code you checked in last night is causing the python bindings to segfault under Linux.  This
happens while importing the vtk module.  I reverted to v1.7 of vtkContainer.cxx and things loaded
correctly.  See GDB output below.

vtkContainer.cxx

Remove the use of vtkString...
