I've tried removing the ticket-workflow section, but then I'm just prompted to upgrade the database and the default workflow is restored. I can't see how ticket-workflow could be missing from trac.ini. If you have any hints, please let me know. I do have a small change to make which should prevent the error in the case that the section is missing from trac.ini. I'll commit that and close this ticket, but please follow-up if you can.
