Hm... That's certainly a change in the meaning of this function. I'm in rather 
a mess currently with the color strategies, so I cannot checkin without 
breaking even more stuff, but try to replace 
KisPaintDevice::convertToQImage() with:

QImage KisPaintDevice::convertToQImage(KisProfileSP dstProfile, Q_INT32 x1, 
Q_INT32 y1, Q_INT32 w, Q_INT32 h)
{
	QImage image;
	QUANTUM * data = new QUANTUM[depth() * w * h];
	QUANTUM * ptr = data;

	if (w < 0)
		w = image() -> widht();

	if (h < 0)
		h = image() -> height();

	// XXX: Isn't this a very slow copy?
        for(Q_INT32 y=y1; y <y1+h;y++)
        {
                KisHLineIterator hiter = createHLineIterator(x1, w, y, false);
                while(! hiter.isDone())
                {
                        memcpy(ptr, (Q_UINT8 *)hiter, depth());

                        ptr += depth();
                        hiter++;
                }
        }

	// XXX: determine whether to apply the monitor profile or based on the copy 
setting
	image = colorStrategy() -> convertToQImage(data, w, h, m_profile, 
dstProfile);
	delete data;
	return image;
}
