In fact, the system freezed again ! Since I saw the message "Erreur de segmentation (core dumped)"
I launched again the command "webbrowser-app" with the var LANG set:
$ LANG=C webbrowser-app
And this time the message was surely the same one without "core dumped". I had not the time to read the error message. For me it seemed to be the same during the small amount of time that I could read it. Then the system freezed like I explained.
Olivier, I have spoken too fast !
