License conflict for VM screensaver (kdeartwork)

[Ben Burton]

Hi,

I was going through the licenses in kdeartwork as part of my debian
packaging, and I came across what seems to be a license compatibility in
the VM screensaver (kvm.kss) in kdeartwork/kscreensaver/kdesavers.

kvm.kss is built from kvm.cpp, vm.c and vm_random.c.

In vm.c we have:

  * Copyright (c) 2000 Artur Rataj
  * Distributed under the terms of the GNU General Public License

And in vm_random.c we have:

  * Copyright (c) 1983 Regents of the University of California.
  * All rights reserved.
  *
  * Redistribution and use in source and binary forms are permitted
  * provided that the above copyright notice and this paragraph are
  * duplicated in all such forms and that any documentation,
  * advertising materials, and other materials related to such
  * distribution and use acknowledge that the software was developed
  * by the University of California, Berkeley.  The name of the
  * University may not be used to endorse or promote products derived
  * from this software without specific prior written permission.
  * THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY EXPRESS OR
  * IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
  * WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

AIUI, this contains an advertising clause (requiring documentation,
advertising, etc to acknowledge UC Berkeley) which is incompatible with
the GPL:

In the meantime I have modified the debian packages to not build kvm.kss,
but if this is a problem then it is clearly not specific to debian.  If
people could either suggest a fix (or explain to me why I'm mistaken) I
would appreciate it.

Thanks - Ben.
