QStandardPaths::ConfigLocation returns wrong paths on Windows

With this program:

#include <QCoreApplication>
#include <QStandardPaths>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    foreach(const QString &path, QStandardPaths::standardLocations(QStandardPaths::ConfigLocation))
        printf("path=%s\n", qPrintable(path));
}

The Qt 5.3 returns:
path=C:/Users/Alexis/AppData/Local/paths
path=C:/ProgramData/paths
path=C:/Products/build-paths-Desktop_Qt_5_3_MSVC2013_OpenGL_32bit-Debug/debug
path=C:/Products/build-paths-Desktop_Qt_5_3_MSVC2013_OpenGL_32bit-Debug/debug/data

but Qt 5.4.2 and Qt 5.5.0 return:
path=C:/Users/Alexis/AppData/Local/paths
path=C:/Users/Alexis/AppData/Local/paths
path=C:/Products/build-paths-Desktop_Qt_5_4_2_MSVC2013_OpenGL_32bit-Debug/debug
path=C:/Products/build-paths-Desktop_Qt_5_4_2_MSVC2013_OpenGL_32bit-Debug/debug/data

The second entry is wrong.
