Comment 14 for bug 16285

I agree with era :)
The problem was fixed in system-tools-backends package which is not used by any kde package:

$ apt-cache rdepends system-tools-backends
system-tools-backends
Reverse Depends:
  gnome-system-tools
  liboobs-1-4
  gnome-system-tools

$ apt-cache rdepends liboobs-1-4
liboobs-1-4
Reverse Depends:
  gnome-network-admin
  gnome-system-tools
  gnome-applets
  moblin-applets
  gnome-network-admin
  liboobs-1-dev
  liboobs-1-4-dbg
