Bug#466704: pointer color is always white

[Glenn McIntosh <neonsignal@memepress.org>]

I understand what is happening now (thanks to Trent W Buck). On the  
current default desktop configurations, applications such as Evolution and  
gnome-screensaver bring in a cursor theme by default (such as  
dmz-cursor-theme in Squeeze). On the cursor theme, the mouse pointer  
colors can no longer be changed. To restore the classic behaviour, it is  
just a matter of turning off the icon theme (set in  
/usr/share/icons/default/index.theme), but of course this means going back  
to the original cursor graphics.
