Mass build failure, font sub-package issue

[Roy Rankin]

The mass build of one of my packages denemo returned a state of failed.
http://koji.fedoraproject.org/koji/taskinfo?taskID=1156407
In fact all builds were successful, but the font sub-package seems to 
have failed registration in some database. The message is as follows:

  pg.DatabaseError: error 'ERROR:  duplicate key value violates unique 
constraint "rpminfo_unique_nvra"
' in 'INSERT INTO rpminfo (id,name,version,release,epoch,
             build_id,arch,buildtime,buildroot_id,
             external_repo_id,
             size,payloadhash)
     VALUES (1029749,'denemo-music-fonts','4.10','1.fc11',NULL,
             85033,'ppc',1235475226,360846,
             0,
             30525,'27dfe803f57d46e4487375d3a0c68bf6')
     '

My understanding is that the main reasons for the new requirement that 
fonts be in a separate package were better license visibility, better 
sharing of fonts, and to save the user from downloading stable fonts 
just because the code changes. And in my case, as the font is in the 
source tar ball a sub-package is indicated.

I gave the font sub-package its own version so code changes would not 
require installing a new font package, and this "protects" the version 
number from rpmdev-bumpspec. However, It looks like doing this is not 
consistent with the Fedora build system.

Is there a way to achieve what I want that will work?
