Sorry, I forgot all that usefull informations. I'm using vpython 3.2.9,=20
compiled from source (I would like to try version 4, but some lib are=20
missing under debian; I'll have to get them from sources).

The crash occurs as soon as I click on the window close box, or if I call=20
scene.hide() or use scene.visible =3D False, but only if there is at least=
=20
one object in the scene; an empty scene does not crash the program.

I may make a mistake using vpython, but the same code runs fine under=20
Windows.

As I said, I'm using debian (lenny). And I'm sure I had this problem some=20
years ago, when I first used vpython (also under debian, but stable sarge)=
=20
for my work: a student made a great 3D view of a complete neutron=20
spectrometer, with real time refresh:

    http://www.gbiloba.org/download/LPA-definitif-640x480.avi

He used it for its presentation, and people where amazed ;o)

Ok. I attached all build logs, and a simple script which fails. I ran it=20
with strace -f (to see all threads).

Thanks for you help.
