  We already knew about at least these and I was told (on #gimp I think)
  that it was not a problem.

 Whoever told you that was wrong.  The text of both licenses includes:
 provided that the above copyright notice appear in all copies and that
 both that copyright notice and this permission notice appear in
 supporting documentation.  This is the advertising clause that is not
 compatible with the GPL.  As a result, these files cannot be distributed
 with the GIMP as they are now.

Wouldn't it only have to appear in documentatoin supporting *the gif and
tiff plugins themselves*, not GIMP in general?  They are, after all,
separate programs.

 I'm not sure how the plugins are used by GIMP.

gimp opens a pipe, spawns the child plugin process, and communicates using
a relatively simple protocol.


 The FSF says http://www.fsf.org/licenses/gpl-faq.html#GPLAndPlugins
 also: http://www.fsf.org/licenses/gpl-faq.html#TOCMereAggregation

 It's very arguable that GIMP and its plugins are effectively one
 program. Especially since GIMP plugins can only be used from GIMP,
 integrate into the mnus of GIMP, etc.

There are other programs that can run gimp plugins. (well, gimp 1.0
plugins at least)

Of course, the question of plugins is almost academic, becuase the
copyright holders of GIMP have explicitly stated that they don't consider
propriatary plugins to be infringing.  If they won't sue over it, who can?

(Note that I am NOT suggesting that we shouldn't make GIMP's licensing
kosher)

   Howdy GIMP folks.  Here are some points in the licensing of GIMP that

  Hmmm...  This is bad, because this is not compatible with the GPL.  So we
  must either stop distributing these files or distribute them in a separate
  package that is not GPL'ed.

 Why is giving credit to an author incompatible with the GPL?

Because GPL gives the end users the free right to modify and
redistribute so long as they obey the GPL license.  They can't
freely modify it if some of the comments or parts of the
documentation can't be deleted or changed because they are
required as adverts.

Admittedly, it's hard to imagine why you'd urgently need to
delete such a thing - but GPL doesn't go into reasons, it
just grants users blanket rights to modify.

For reasons not to start subtly modifying the GPL, read
about all of the horrible things that are happening to Wine,
WineX and ReWind!  If they'd used an unmodified GPL from
start to finish, none of that would have happened.

It's not the credit-giving (typically, authors usually credit themselves
in the file header) but the requirement of prominent advertizing. I'm not
a license guru, but I think the GPL explicitly forbids extra
license requirements above those specified in the GPL itself. So if you
want an advertizing clause, you have to use a modified version of the GPL
or combine the code with a modified version of the GPL, thus non-GPL.

In fact, when I now searched gnu.org, I found this:
http://www.gnu.org/licenses/gpl-faq.html#TOCOrigBSD


 I see no reason why an advertising clause need cause an issue...
 could someone explain it to me?

This is most likely not the proper list for general licensing discussions
or questions. I'm sure there are better suited lists for that.
