That code was written for integrating into KDE 4.
It was not adapted to work with Plasma 5.

A pure KF5 appliation would anyway use the KDE platform theme plugin provided 
by KDE Frameworks.  (in frameworkintegration)
(So in other words: that code should not be executed when kde frameworks is 
installed, in theory)
