Licences with mutually exclusive terms
Is it true that a copyright licence with mutually exclusive terms are
non-free? Further, is a licence saying:
You may prepare, copy and distribute derived works of this software.
However, you may not modify this work.
...specifying mutually exclusive terms? What does it mean.
I am particularly interested in past cases; either discussions on
debian-legal, or from the courts. I realise this may be off-topic for
debian-legal. If I get replies off-list, I will summarise them.
Many thanks in advance for any help,
