Bug#677047: confirmed in kdm 4.8.4-2

[Andreas von Heydwolff <106624.446@compuserve.com>]

While updating an old installation of kde 4.5 to Wheezy's current kde I
experienced the same problem. The faces dir was missing altogether. Running

  # genkdmconf

at first only created /usr/share/kde4/apps/kdm/faces/root.face.icon
(and perhaps .default.face.icon - in retrospect I may have omitted to
use # ls -a to see the hidden file).

After purging the package and deleting any remaining dirs and
reinstalling, the faces dir was missing again. Now running

 # genkdmconf

again created the directory /usr/share/kde4/apps/kdm/faces/, the

  root.face.icon

and also the file

  .default.face.icon

Greetings
Andreas
