QtCreator debug helpers fail and show "d" as children of objects

I'm trying to debug a simple Qt program using QtCreator. The problem is that the debug helpers don't work for Qt Objects and instead of their contents I only get "d" as child ( see attached screenshot ).
I should mention to I had GDB with not python support but I've since recompiled it and it should be OK now. There are no errors I could find in the attached log to indicate a serious failure but it doesn't work.
Debug log is attached, let me know if you need more info.

Thank you.
