HVD Comic Serif Pro: licensing confusion

[J.B. Nicholson-Owens]

I found HVD Comic Serif Pro on the wish list of fonts to be reviewed and 
packaged for inclusion into Fedora GNU/Linux.

https://fedoraproject.org/wiki/HVD_Comic_Serif_fonts

I downloaded a copy of the font archive file -- 
http://hvdfonts.com/assets/Document/15/HVD_Comic_Serif_Pro.zip -- and I 
read the Readme.txt file therein.

That Readme.txt file includes terms which conflict with the license:

> This typeface may not be modified in any way unless it contains an
> unmodified copy of this text file and attributes Hannes von Döhren in
> the font metadata.

and

> Neither the Font Software nor any of its individual components,
> in Original or Modified Versions, may be sold by itself. Original or
> Modified Versions of the Font Software may be bundled, redistributed
> and/or sold with any software, provided that each copycontains the
> above copyright notice and this license

conflict with portions of the license (for the font, I can only guess) 
which is listed as:

> LICENSE:
> "This work is licensed under the Creative Commons Attribution 3.0
> Unported License. To view a copy of this license, visit
> http://creativecommons.org/licenses/by/3.0/ or send a letter to Creative
> Commons, 171 Second Street, Suite 300, San Francisco, California, 94105,
> USA."

The top two passages I quoted above seem to me to be licensing terms. 
And these terms conflict with CC BY 3.0 unported:

- there is no requirement in this CC license which requires a licensor 
to include "an unmodified copy of this text file"

- there are no restrictions in this CC license against distributing 
copies of this font alone for a fee

- attribution in accordance with this CC license can be achieved without 
including this Readme.txt file (one could, for example, include no such 
file and list changes elsewhere, or include a different readme.txt file 
which gives Hannes von Döhren credit and list changes in that different 
file)

- this CC license says it is the only set of terms for licensing this 
work under this CC license (sections 4a and 8e).  My reading of these 
sections say that any other terms (such as those listed in the 
Readme.txt file) do not have to be followed.

Looking at https://fedoraproject.org/wiki/HVD_Comic_Serif_fonts it seems 
that Fedora considers CC BY 3.0 unported to be the only operative 
license on this font.  But how has Fedora determined that this 
Readme.txt file can be ignored?  I looked through the mailing list 
archives for this list and found no discussion referring to this font.

Has anyone contacted Hannes von Döhren about this?

Thanks.
