Mass virtual hosting and global redirect

There you go:

And here's a strace:

Nginx gives 500 error, as you can see, while it works perfectly using the if's. To be noted, it works perfectly if I try to access any URL deeper than first level (www.domain.com/something works, www.domain.com or www.domain.com/index.php does not).
