Yes, I did have a ~/.fonts.conf file. I don't remember ever creating it, and definitely didn't put it there myself while running Edgy (so it would have been there in Dapper, but I didn't have these problems there). I've removed it and fonts in konsole, firefox, kmail are all fine. Thank you. Apologies for filling this bug with bogus info!
