I'm using KDE 3.4.2b with Qt3.3.4
I'm using the crystalsvg icon theme

I was actually just initializing the KPushButtons with the (KStdGUIItem::KGuiItem*,QWidget*,const char*); constructor, which does seem to work since it adds text labels, but adds an empty icon...

I solved the problem for now by using KGlobal::iconLoader() to look for icons, but still don't have neat add or remove icons and settled for "ok" and "cancel" for the time being;
