How to properly setup Source Paths Mapping in QtCreator for Qt 5.0.1

Hi, I just downloaded and installed Qt 5.0.1 for Windows 32-bit (MinGW 4.7). If I build a debug version of an example in QtCreator 2.6.2 (i.e. cube example) I can debug the example code but I cannot step into the Qt sources (i.e. widget.show()). I guess that I need to setup Source Path Mappings in QtCreator but I don’t know what to enter for source and target path. I installed Qt 5.0.1 to C:\Coding\Qt5.0.1. That means the root directory of the installation that contains InstallationLog.txt is C:\Coding\Qt5.0.1. If I press the QtCreator button Add Qt sources… it adds the source paths C:\iwmake\build_mingw_opensource and C:\ndk_buildrepos\qt-desktop\src. But I’m not sure wich target paths to enter here. I tried C:\Coding\Qt5.0.1\5.0.1 and C:\Coding\Qt5.0.1\5.0.1\Src – but none of them worked and I still can’t step into Qt functions. Any idea how to properly setup source paths mappings to debug Qt 5.0.1 source code.
