Description swell.k 2011-03-01 01:50:11 UTC
FreeBSD by default tries to use IPv6 address for localhost
according to r64664 for /etc/hosts

  ::1			localhost localhost.my.domain		localhost localhost.my.domain

as transmission-remote doesn't support IPv6 yet (see ticket#2236) the
connection may fail

  $ transmission-remote -l
  [04:25:19.761] transmission-remote: (http://localhost:9091/transmission/rpc/) Couldn't connect to server

or hang if net.inet.tcp.blackhole > 0

  $ truss transmission-remote -l
  connect(3,{ AF_INET6 [f4ac:c301:800:0:10::]:16391 },28) ERR#36 'Operation now in progress'

FYI, similar issue was fixed in firefox-devel + PGO in freebsd-gecko repo

  - Fix PGO build on systems where IPv6 is enabled. The SimpleHTTPServer
    binds to an IPv4 address only so force the browser to connect via

but I'm not sure what causes this in transmission-remote case (libevent?).

Makes sense, I even have replied to transmission ticket #2236 to use your 
patch until then. Committed, thanks!

It's likely related to libcurl as I can't reproduce it when ftp/curl is
compiled WITHOUT_CARES, cf.
