QPainter::drawPixmap is causing a segmentation fault

When I scale a painter in 131072 times and try to draw a pixmap on it, it crashes.

The example is very simple (there is a small compilable file in the attachment):

painter->scale(131072, 131072);
painter->drawPixmap(0, 0, pix);

Probably it is a regression
It works on 4.5.3, but it doesn't work on 4.6.X and 4.7.

I test it on Linux X11 and Symbian.

ps: It works with -graphicssystem opengl. It can be a clue =)
