Description of problem:
A HTTP proxy with an ignore list is configured in gconf.  Evolution is
configured to use a webcal on from a host that should not go through the proxy.
 But apparently, evolution-data-server still tries to go through the proxy when
fetching this webcal.

Version-Release number of selected component (if applicable):
evolution-data-server-1.8.0-15.0.4.el5

How reproducible:
Every time

Steps to Reproduce:
These are my settings:

gora$ gconftool-2 --recursive-list /system/http_proxy
 use_http_proxy = true
 use_authentication = false
 host = m460
 ignore_hosts = [localhost,127.0.0.0/8,192.168.0.0/16]
 authentication_user = 
 authentication_password = 
 port = 80

gora$ host m460
m460.carmen.se is an alias for clavister-m460.carmen.se.
clavister-m460.carmen.se has address 192.168.100.250
clavister-m460.carmen.se mail is handled by 10 clavister-m460.carmen.se.

gora$ gconftool-2 --get-list-element  /apps/evolution/calendar/sources 1
<?xml version="1.0"?>
<group uid="1171639857.7855.6@gora" name="P&#xE5; webben" base_uri="webcal://"
readonly="no"><source uid="1176360708.17627.0@gora" name="Helgdagar"
relative_uri="wiki/ical/Svenska-Helgdagar.ics"
color="ff0000"><properties><property name="alarm" value="false"/><property
name="refresh" value="720"/></properties></source></group>

gora$ host wiki
wiki.carmen.se is an alias for honolulu.carmen.se.
honolulu.carmen.se has address 192.168.98.24

Actual results:
When I start evolution, I get an error message "Error on
webcal://wiki/ical/Svenska-Helgdagar.ics: Service Unavailable"

Additional info:
I attached an "strace -f" to my bonobo-activation-server.  In the log I see
these lines (cutting out a lot, obviously):

19089 clone(child_stack=0,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x41e439d0)
= 19090

19090 execve("/usr/libexec/evolution-data-server-1.8",
["/usr/libexec/evolution-data-server-1.8",
"--oaf-activate-iid=OAFIID:GNOME_Evolution_DataServer_InterfaceCh"...,
"--oaf-ior-fd=19"], [/* 73 vars */] <unfinished ...>

19090 socket(PF_INET, SOCK_STREAM, IPPROTO_IP <unfinished ...>

19090 <... socket resumed> )            = 27

9090 connect(27, {sa_family=AF_INET, sin_port=htons(80),
sin_addr=inet_addr("192.168.100.250")}, 16 <unfinished ...>

19090 <... connect resumed> )           = -1 EINPROGRESS (Operation now in progress)

19090 write(27, "GET http://wiki/ical/Svenska-Helgdagar.ics HTTP/1.1\r\nHost:
wiki\r"..., 96 <unfinished ...>
19090 <... write resumed> )             = 96

Note how it connects to 192.168.100.250 which is host m460 rather than directly
to host wiki on 192.168.98.24 as I would have expected.

I've tried with various settings in the ignore list, mentioning the wiki host
explicitly for example.  But it doesn't seem to make any difference.
