Thanks for the info!  I have found that there are some other issues I
am trying to solve before submitting to gerrit. I did sign the CLA so
that I can contribute it. Hopefully this week will make sense to
submit it.

Actually, perhaps you have a bit of advice on this.  The fix in that
patch makes it so that horizon cannot create new flavors (because of
the way it detects the "highest" number flavorId); when dealing with
problems like this that span projects with strange side effects, does
it make sense to make the bug "affect" the other project and try and
submit a patch for both (via gerrit) on the same bug?  I am trying to
wade through the best practices of OpenStack for this type of stuff
and any advice would be welcome!

Thanks!
