All the proxy stuff is actually done by kio_http. khtml does not have
network code on its own. The way to enable the proxy is to set 
UseProxy metadata to the proxy URL in the kio_http job.

The code reading the settings (and hence the setting names) is here:
http://lxr.kde.org/source/KDE/kdelibs/kioslave/http/http.cc?v=3.5-branch#279

It seems like you're doing the right thing here, though --- the SlaveConfig
stuff (assuming self.slaveConfig is the KIO::SlaveConfig singleton object)
is supposed to set the default metadata, and KHTML does not touch 
the proxy metadata. 

If your KDE is built w/o NDEBUG, turning on debug area 7113 in kdebugdialog,
and running kdeinit from a terminal (so you can see the output) may also
offer some insight.

If you're working with KDE4, and alternative is the 'startingJob' virtual in
KHTML which can be overriden, to set those sorts of things, but it doesn't
appear to be available in 3.x. 

Sorry that I couldn't be more helpful, but I am seeing this part of KIO for
the first time..
