[Toulibre] visite virtuelle de la cité interdite

[jdebars]

sur le site : http://virtualforbiddencity.org

j'ai téléchargé le rpm VirtualForbiddenCity.rpm

comme je suis sous Ubuntu 8.04, avec "alien", j'ai fait un .deb (avec ou 
sans l'option --scripts )

pour le lancer, j'exécute directement le 
/opt/VirtualForbiddenCity/vfc-run.sh

j'ai le message d'erreur suivant

pop-up : Fatal-ISV: (gui/controls/guiBrowserCtrl.cc @ 656)
message : Error initializing embedded browser 1401

est-ce que quelqu'un à une solution ?

A+
Jacques

remarque : j'ai une carte Nvidia Geforce MX 440 et un écran plat en 
1280X1024 depth 24
