I hope this is not true, otherwise it would be a RC-bug.
According to http://www.gnu.org/philosophy/gif.html
the Unisys patent
| does not expire in most of Europe until 18 June 2004, in Japan until
| 20 June 2004 and in Canada until 7 July 2004.
(It is expired in the US.)
(That is the cause why ppmtogif will stay in netpbm-nonfree until 7 July 2004, so it's not in netpbm-free at sarge release.)

(RM adds: The last patent believed relevant to LZW compression was one IBM held in the USA. It expired in August 2006.
