Error when viewing ticket

[anonymous]

I just installed AnnouncerPlugin-trunk and whenever I try to view a ticket I get the following error

How to Reproduce

While doing a GET operation on /ticket/3, Trac issued an internal error.

Scratch that... it's an issue with babel. My apologies

No problem, but if you could give more details about the solution, it might be helpful. Maybe we could add better error handling? Or at least if someone else hits the issue you could leave the solution here.

I have the same error, but I did not install any third party plugins at all. The error appears when I want to view the detail page of a ticket. I also got this error when creating a new ticket, but the ticket was created anyway. I can see the tickets in the timeline and in the ticket reports page, but i cannot access the detail page.

Stop. So why do you bother reporting here? This is the wrong Trac instance for reports against Trac core, please go to trac.edgewall.org instead. Thanks for taking care.

It seem to spring from configuration, so my best bet is, that's an local configuration error in your [ticket-workflow] section.

Sorry for not reviewing that ticket much sooner. The previous author/maintainer is no longer in town to take care.
