gtk-qt-engine 1:1.1+svn20080816-0ubuntu6 (i386 binary) in ubuntu jaunty

 The GTK-Qt Theme Engine (also known as gtk-qt-engine) is a GTK+ 2 theme engine
 that calls Qt 4 to do the actual drawing. This makes your GTK+ 2 applications
 look almost like real Qt 4 applications and gives you a more unified desktop
 experience.
 .
 Please note that this package is targeted at KDE 4 users and therefore provides
 a way to configure it from within Systemsettings.
