QDesktopWidget doesn't emit any signal at screen resolution change or monitors count

Question

I'm testing on Mac OS 10.9.1 with Qt 4.8.5 The same code works on Windows and I'm pretty sure it worked before update from the MacOS 10.8.

private slots:

void desktopResized(int screen);
void desktopScreenCountChanged(int newCount);

...

bool result = connect(qApp->desktop(), SIGNAL(resized(int)), SLOT(desktopResized(int)));
Q_ASSERT(result);
connect(qApp->desktop(), SIGNAL(screenCountChanged(int)), SLOT(desktopScreenCountChanged(int)));

Slots just never get called on change of monitor resolution. Does anyone have the same problem, any solution? Thanks

[UPDATE] The bug is resolved in Qt 5.2.1
