Crash in QPixmap(QImage) constructor (Qt 4.6 RC1 regression)

The QPixmap constructor that accepts a QImage argument (Qt3Support) crashes because of a NULL pointer. Seems like the code did not get adapted when QPixmap::init() got rewritten for Qt 4.6. Previously it always had a value, now it is set to NULL because of the arguments passed.

Simple to reproduce (with QT += qt3support set):

#include <qapplication.h>
#include <qpixmap.h>
#include <qimage.h>

int main(int argc, char **argv)
{
QApplication a(argc, argv);
QImage img;
QPixmap pix(img); // <-- will always crash
}
