[Cooker] 7.1 installation problem

[Timothee Besset]

I'm installing 7.1 (not cooker) from the network. I came accross a bug 
while doing a custom install, a "fatal error, division by zero". I tried 
again with Automated install and it works fine so far. Sorry I don't 
have more details, just to let you know in case you can quickly fix 
something before announing 7.1
