I haven't investigated thoroughly. It's possible that _post_process_request in trac.web.main needs to handle the error.

[Ryan J Ollos]

post_process_request is called with the Request object as the only argument after an exception is raised processing the request: ​trac:browser:tags/trac-1.0.6/trac/web/main.py@:257,261-263#L253. The exception is raised again when req.path_info decodes the path in VotePlugin's post_process_request.

After [14703] the logic in VotePlugin's post_process_request will be skipped when it is called after an exception is raised. Therefore the traceback should not be seen. Closing as a duplicate of #12105.
