Well, the info provided by Rafael does offer us a good starting point since by 
looking at kmimetype.cpp 
(http://websvn.kde.org/trunk/KDE/kdelibs/kdecore/services/kmimetype.cpp), 
it's possible to get an impression what is done within the 
KMimeType::iconNameForUrl() method to map a URL=>mimetype=>icon.

It seems there may also be an easier way by just replacing in the mimetype "/" 
with "-" (so, e.g. image/png becomes image-png) and then look what the 
KIconLoader::iconPath() method 
(http://websvn.kde.org/trunk/KDE/kdelibs/kdeui/icons/kiconloader.cpp) is 
doing.

So, within a Qt-app it may needed to emulate/extract what findResource() does 
and to probably also try to fetch the information what icontheme is used 
(e.g. oxygen) to select the correct one.

here the commandline version (thx dfaure for the hint provided at another 
mail ;)
kiconfinder `echo image/png | sed -e 's,/,-,g'`
