Qt WinRT: Not able to start QThread

I recently installed Qt 5.4 RC. I am facing an issue with QThread. QThread::start() function never returns. It just hangs there. For example in the below code snippet:

void EmulatorTest::threadTest(){ QThread thread; qDebug() << “starting thread”; thread.start(); qDebug() << “thread started”;
}
The debug statement “thread started” never gets printed and my application hangs.

I am using Qt for winrt and I have tested the above code in both windows emulator and windows phone.
