From what I've read in the thread I mentioned before this means that mpd code 
must be opening one socket for IPv4 and another for IPv6.

But this only happens if I set bind_to_address to "any" in /etc/mpd.conf. If I 
leave "localhost" then both ports open. Here's an mpd bug for sure. 

Tested with two machines, one a quite recent setup.

Nor the value of BindIPv6Only in mpd.socket nor the value of bind_to_address 
in /etc/mpd.conf.

Also tested in two machines.

And my apologies for such many mails, but at least we have something to look 
at now.
