Details:

Server won't start from freeciv-gtk3 client version 2.5.0
Says, you have to do it manually, sorry.
I checked before and after, that ports 555* are free.
freeciv-server starts ok and I can connect to my game
There is an 2.3.2 Freeciv installed form Wheezy on the system.

Follow-up Comment #1, bug #23392 (project freeciv):

Problem is the --bind localhost
freeciv-server won't start
--bind 127.0.0.1 does start

I have compiled with ipv6=no

~$ grep localhost /etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback

Follow-up Comment #2, bug #23392 (project freeciv):

More problems with --bind, related or not.
freeciv-server --bind 127.0.0.1 restricts the server on lo
freeciv-gtk3 can see the server but won't connect: connection refused

Without the --bind it can see the server AND connect.

--quitidle 1 won't quit the server in 1 second

bind(3, {sa_family=AF_INET, sin_port=htons(5557),

sin_addr=inet_addr("127.0.0.1")}, 16) = 0

...
bind(4, {sa_family=AF_INET, sin_port=htons(5557),

sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EADDRINUSE (Address already in
use)
So it's trying to bind to the same address twice.

--bind 127.0.0.1 does start
I have compiled with ipv6=no
~$ grep localhost /etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback

I can reproduce on Ubuntu 14.04 with Freeciv 2.5.0 compiled with
"--enable-ipv6=no" (but HAVE_GETADDRINFO defined) with /etc/hosts having
entries for "localhost" mapping to both 127.0.0.1 and ::1, but not with my
standard /etc/hosts (where localhost only names 127.0.0.1).

What system/distribution are you running on?

Follow-up Comment #5, bug #23392 (project freeciv):

I can positively confirm that, with a ripped-out hosts file, the bug does not
occur. That is,

->-- /etc/hosts ----
127.0.0.1 localhost
--<-----------------

Server trace in this case shows the second bind call

bind(4, {sa_family=AF_INET, sin_port=htons(5557),

missing.
