I had the same problem when running dev/build on the upgrade. It turned out to have been caused by lowercase table names.
To clarify, I had the issue when upgrading on my development machine, which is a Macbook--but I had copied the database and files over from a Windows machine, which had converted the table names to lowercase.
I replaced the database with a correctly capitalized copy from the live site, and then everything worked fine. The upgrade went smoothly on the live site.
