Wrong parameter type in ticket/web_ui.py in method _process_ticket_request

[anonymous]

Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/Trac-0.11.1-py2.6.egg/trac/web/main.py", line 423, in _dispatch_request

TypeError: unsupported operand type(s) for %: 'Fragment' and 'tuple'

I solved this problem this way:

add_warning(req,
tag(tag.p('Please review your configuration, '
         'probably starting with'),
    tag.pre('[trac]\nworkflow = ...\n'),
    tag.p('in your ', tag.tt('trac.ini'), '.')).__html__()
