Bug#358350: konqueror: proxy auto configuration => problem with multiple proxies

[Das Supportteam <support@math.uni-bonn.de>]

Package: konqueror
Version: 4:3.3.2-1sarge1
Severity: normal

We're using the proxy autoconfiguration to have the same proxy config on 
firefox and konqueror.
We have a primary proxy and a backup proxy. Both are returned by the script.

We're following the documentation at:
http://wp.netscape.com/eng/mozilla/2.0/relnotes/demo/proxy-live.html
which is also referenced in the admin documentation of the kde project.
(http://i18n.kde.org/docs/admin/admin.txt)

The Problem is that the first proxy is offlien due to hardware problems 
and konqueror ignores the second entry. The documentation states that it 
uses the next entry if the current proxy is dead. Firefox does this. 
konqueror complains that it's not possible to reach the first proxy and 
stops.

pac file looks like this:
function FindProxyForURL(url, host)
{
direct = "DIRECT";
proxy  = "PROXY proxy2.math.uni-bonn.de:3128; PROXY 
proxy3.math.uni-bonn.de:3128;";

        if (!(dnsDomainIs(host, ".math.uni-bonn.de") || 
isPlainHostName(host)))
                return proxy;
        else if (!isInNet(host, "131.220.120.0", "255.255.255.0"))
                return proxy;
        else
                return direct;
}

(The proxy=... row is not wrapped in our script!)

There seems to be a wrapper class for the pac stuff
(http://developer.kde.org/documentation/library/3.0-api/classref/kio/KPAC.html).
It looks like this class is broken or it's used in a wrong way in konqueror.

We tried to change the name of the first broken proxy to another 
computer that is turned on but has no squid running (to check if there 
is a difference between host offline or no port open)
