I've tried to activate ipv6 module but it doesn't change anything.
I'm not sure it's because of the ipv6 adressing on the network router, but at 
home connected to my internet provider internet box, the adressing mode is 
ipv4, and ther is no problem.
I've tried to trace connection to the port used bby webiopi (8000) with 
netstat, but it's not used. I've also tried to change the default port number 
(switching it to 8001), but it doesn't make any change to the error.

Any help is appreciated.

Thanks!

Try this :
sudo update-rc.d webiopi remove
sudo reboot

sudo /etc/init.d/webiopi start
