What should KGlobal::config() be when it doesn't know what name you want
to use?
The same with KLocale, KStandardDirs (which needs KConfig :) and
KIconLoader.
They all need to know the name of your application. If you need
something of these
before you have the KApplication, create a KInstance with the same name.
KInstance
is only about the name. 

You're right, that the self() pattern isn't implemented properly.
