Splash Screen crash in device

I made a small test of Splash Screen as the code below:

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QSplashScreen mySplash;
mySplash.setPixmap(QPixmap(":/fedora.png"));
mySplash.show();

SplashScreen w;
w.showMaximized();
mySplash.finish(&w);
return a.exec();
}

On the emulator it work fine but when run on device ( N71, E63 ) it makes device hang (must remove the battery to restart ).

I'm using : S60_3rd_FP2_SDK_v1.1
qt-symbian-opensource-4.6.2
Carbide.c++_v2.3
Tested in Emulator and Nokia E63, N71.
