It's a problem with art.gnome.org, it reject the connection (may by an IDS or
L7 Firewall)
I show strace:

And the tcp traffic:
$ sudo ngrep -d ath0 port 80
interface: ath0 (192.168.23.0/255.255.255.0)
filter: (ip or ip6) and ( port 80 )
####
T 192.168.23.142:45793 -> 209.132.176.176:80 [AP]
GET / HTTP/1.1..Accept: */*..Host: art.gnome.org....
#
T 209.132.176.176:80 -> 192.168.23.142:45793 [R]
......
So I try to connect to art.gnome.org with:
1) Firefox: Works
2) Links (text based): Works
3) Netcat:
nc art.gnome.org 80
GET / HTTP/1.1
and the server reset de connection.
So I think the program needs more HTTP Headers.
