Harmattan target -> "no such file or directory" for #include

For all the "qt includes" (e.g. #include <QtDeclarative>) you get "No such file or directory" and the code assistant doesn't work while editing cpp files. I am able to build even with the errors - it is just a problem with the editor apparently.

I tried to remove and re-install. Also tried to install to a different hard drive.
If I change the target to "desktop" the editor works just fine.

Steps to reproduce the issue:
1. install qt sdk 1.1.2
2. create new project (qt quick project\Harmattan application)
3. open main.cpp

The two include lines
#include <QtGui/QApplication>
#include <QtDeclarative>

will be underlined and by moving the mouse over you will get a tool tip "no such file or directory".
