Is there a problem with using QIcon::setThemeName("Oxygen")? It you want to 
use the system defined theme Qt needs to detect the desktop platform and at 
least the KDE platform theme already defaults to Oxygen. 

If that is not enough, it might be possible to add some kind of QIcon fallback 
theme setting.
