[Bug 908065] [NEW] QImage and QPixmap alpha channel is black with .fill()

[prof_ebral]

Public bug reported:

I am unable to make the alpha channel appear transparent with a QImage
and a QPixmap when I use the .fill() method, all I return is black. With
a QImage formatted to ARGB32 I am able to set the .fill method with
argument 0 and the image will fill with transparent pixels ... just not
on Ubuntu. (tested on Fedora 13, Fedora 15, Windows XP). With QPixmap I
use the fill method with argument Qt.transparent and the same results
(same tested OSs).
