Problem to find some pkg-config libraries

qtcreator 2.6 has the regression outlined in the attacched image.

I'm using gstreamer inside a qt console app gstreamer is linked using:

CONFIG += link_pkgconfig
PKGCONFIG += gstreamer-0.10

the project compile and run fine but no autocompletion is available, works fine in qtcreator 2.5 so this is a regression

the problem is reproducible creating a new qt console project adding the above lines to the pro file and including "gst/gst.h" in main.cpp, the project will compile but no autocompletion will be available,
