Using the possiblility to use precompiled headers results in problem entry in stdafx.h

If you create an Qt5 app with precompiled headers you get
#include “QWidgets” in the stdafx.h which is not possible to be compiled because QWidgets can not be included by the preprocessor. Can I but this to a bug report or how a bug is reported.

Digia's note. Incorrect additional include directories paths are set when Qt modules added/removed from Qt Project Settings page. Also on first time if Qt Version is not yet set, all the additional include paths are totally removed. This causes the reported problem with precompiled header.
