I just looked at the bug and I have the feeling that the patch is wrong, but I 
cannot verify as I don't have multiple X screens. It clearly is potentially 
crashy as it uses the iterator over the views is a valid index of the screens 
by QDesktopWidget.

The real question is: why is the user using multiple X screens (out of 
experience: in 101 of 100 cases it's not what the user wants ;-)
