QDir() behavior is broken

Empty QDir() returns user home dir while program working dir should be returned. This breakes QFileInfo behavior as well.

Code:
#include <QCoreApplication>

#include <QDir>
#include <QDebug>

int main(int argc, char *argv[])

{ QCoreApplication a(argc, argv); qDebug() << QDir().absolutePath() << a.applicationDirPath(); return 0; }
