I had this too in 4.0.11, but not in 4.0.9. I noticed the database was getting created, but not the tables within.
I think the problem is that the wp_config.php file has the wrong root password. I changed it from 'password_here' to '' and then the site worked fine, and I was presented initially with the worpdress language selection page.
Hope this helps, and maybe a fix is in order for 4.0.12...?
