Not just a black rectangle, but the screenshot can also show a window
that is actually behind the other ones (i.e. a window that should be
completely invisible). I've added:

Key g           A       CM      Exec gnome-screenshot

so that I could take a screenshot with imagemagick and another one
with gnome-screenshot, and only the imagemagick one is buggy.
