"TracError: Access denied" when tickets are viewed in Text format

[fungbat@…]

The following error occurred for the user with TICKET_VIEW_GROUP permission. Initially, the ticket report showed fine. But when one clicked to download the report in other format (comma and tab delimited text), the following error resulted:

Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 387, in dispatch_request
    dispatcher.dispatch(req)
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 191, in dispatch
    chosen_handler = self._pre_process_request(req, chosen_handler)
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 263, in _pre_process_request
    chosen_handler = f.pre_process_request(req, chosen_handler)
  File "build/bdist.linux-i686/egg/privatetickets/report.py", line 19, in pre_process_request
TracError: Access denied

Somehow, the RSS format seems to work fine.

Thats a feature. Filtering the tab and csv formats would have been significantly more complex, and I don't have a need for it, so I just block them.
