no longer a bug.
from the documentation in question:
"Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.2 or
any later version published by the Free Software Foundation; with the
Invariant Sections being ``GNU General Public License'' and ``GNU Free
Documentation License'', with no Front-Cover Texts, and with no
Back-Cover Texts. A copy of the license is included in the section
entitled ``GNU Free Documentation License''."
The only things the documentation license holds as invariant are the GPL
and the GFDL themselves, and Debian already accepts those as being
invariant, this documentation should no longer be considered non-free in
light of GR-2006-01. But becuase of this, I'm copying debian-legal.
