You should ask to whoever provided Qt4 packages to you. Kubuntu, in your case.
Hi, I had the same issue and nailed down to the Trolltech.conf file in your ~/.config/ folder. Just rename this file to e.g. Trolltech.conf_broken and then start the application (e.g. I've tried with VirtualBox and Lyx) and it should be fine. Cheers, Damijan Bec
