The delayed iconset loading was added by Lubos quite some time ago. My commit 
to KInstance (together with kiconloader.cpp, rev. 206) only changed the 
default KIconLoader to not use delayed iconset loading. Only KIconLoaders 
created by a KInstance do this. 

The reason for this is that some people not knowing about 
KGlobal::iconLoader() create a temporary iconloader to load icons. Delayed 
loading via KIconFactory crashes in that case, as the iconloader is already 
destroyed and the factory therefore uses a dangling pointer.
