Hi,

what should you do, when you need stuff from KGlobal, but you're not
having a KApplication?
E.g. currently you can't use KConfig without a KInstance/KApplication,
because KConfig uses KGlobal::dirs(), which is only available when there
is a KInstance.

Should anyone needing KGlobal, KConfig and most possibly other classes
before KApplication create a temporary KInstance itself? The destructor of
KInstance should then set KGlobal::_instance to 0, so that the KApplication
object can become the next KGlobal::_instance.

And we'd need to have a policy: before calling any methods in kdelibs, you
need to have either a KInstance or KApplication.

Is this correct?

Cheers,
Carsten Pfeiffer
