Bug#385849: Need policy compliant way to enable custom kdm theme for debian edu

[Petter Reinholdtsen <pere@hungry.com>]

I've discovered that I also need to update /etc/kde3/kdm/backgroundrc
to make sure the background image do not flicker back and forth when I
use the same background image in KDE an the KDM theme.  It would be
nice if I could do this too in a policy compliant way.

  /usr/bin/update-ini-file /etc/kde3/kdm/backgroundrc 'Desktop0' Wallpaper debian-edu-wallpaper.png

For this background I could use divert to replace
debian-kde_default.png, or perhaps the KDE packages should provide
/usr/share/wallpapers/debian-kde_default.png.desktop as an
alternative, to make it easier to replace it in artwork packages?  For
the KDM theme, The UseTheme flag need to be changed to 'true' before
any divertion or alternative could do the job, so I am still searching
for a policy compliant way to do that.

Friendly,
