Well no it's not broken, it works fine and this mechanism is used in other places (e.g. kpixmapprovider iirc).

This is a hook for applications like kontact, which can reimplement the behavior. 
kontact creates and instanciates a derived class, which sets it as the singleton instead of the kdelibs one,
and everything goes through it instead of using the default implementation from kdelibs.
