internal errors on view and create new ticket

[vittorio]

i get following when trying to view a ticket:

Traceback (most recent call last):
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 492, in cgi_start
    real_cgi_start()
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 487, in real_cgi_start
    dispatch_request(path_info, args, req, env, database)
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 397, in dispatch_request
    module.run()
  File "/usr/lib/python2.1/site-packages/trac/Module.py", line 45, in run
    self.render()
  File "/usr/lib/python2.1/site-packages/trac/Ticket.py", line 404, in render
    self.insert_ticket_data(self.req.hdf, id, ticket, reporter_id)
  File "/usr/lib/python2.1/site-packages/trac/Ticket.py", line 327, in insert_ticket_data
    evals = dict(zip(ticket.keys(), map(lambda x: escape(x), ticket.values())))
NameError: global name 'dict' is not defined 

and this when trying to create new ticket:

Traceback (most recent call last):
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 492, in cgi_start
