Hi Julien, I'm really sorry for the long delay, but I've finally managed to get a backtrace from gdb with this command:
printf 'continue\nbt full\nquit\n' | nohup sudo gdb -p `pidof Xorg`
The result are attached. Please tell me if you need anything else to
debug this crash!
Best regards
Alexander Kurtz
