Thanks for those remarks.
For:
gSystem->Load("libGeom")
gGeoManager->Import(...)
yields a null pointer
that's why I left the empty TGeoManager call for both examples. Sorry, I can't make out the perfect way myself...

Well, just a few days ago I remember getting the _interactive_ viewer from inside
an interactive python shell (no matter if python -i or ipython). I was hit by "display-list registration failed only recently, but, I must admit I do not know what change triggered that... Can I ask what do you mean by "exiting python"? If I really Ctrl-D the python shell I kill all the windows created "from inside" this python session, including the 3D viewer created.
