I can't reproduce. Any idea of what conditions led to this?

[Ryan J Ollos]

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.

(In [12217]) Fixes #10143:

• Replaced access of the private field _sections in the Configuration object with proper access to the keyed item. The issue described in #10143 has not been reproduced, but this change should avoid a traceback if there is a case in which the ticket-workflow section is missing from trac.ini, because an empty Section object is constructed in the Configuration class under this scenario.
• Applied formatting changes to setup.py.
