I see nothing wrong in your config. It's so simple! Could you check a few things, such as if something already exists in /var/run, if you see a symbolic link or anything like this which might explain such a strange behaviour.

Also, it would be nice if you could start haproxy under strace :

# strace -o /tmp/haproxy-start.log haproxy -db -f /etc/haproxy.cfg

Then press Ctrl-C after a few seconds, and look for "haproxy.stat" in the output file (or post the result here). I think we'll find the reason there. There must be an error somewhere, or there is something disabling the stats but I don't see what can do that.
