Comment 21 for bug 223274

Sadly, gtk-qt-engine is a quite broken piece of software and has been removed from distribution. (See bug 404930)
Unfortunately this means that the large number of bugs will not be seeing fixes. :(

For now, the best integration option for KDE is the QtCurve style, (gtk2-engines-qtcurve) which offers a theme quite similar to the default Oxygen theme. The configuration module for gtk-qt-engine has been salvaged and is now living in the kcm-gtk package, which will be available and installed by default in Kubuntu 9.10.

Thanks for understanding. This package tried its best, but in the end did not live up to the standards required by anybody who doesn't like looking at a broken Oxygen imitation.
