How to register the Trac?

[Takashi Yamamiya]

Hello,

I tried to register the Trac at http://dev.laptop.org to use bug tracking,
but I couldn't do it. Did I miss something, or for any bug?

1) When I tried to register and and login, this error message is
   appeared (the account name was "Takashi").

Python Traceback

Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 335, in dispatch_request
    dispatcher.dispatch(req)
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 193, in dispatch
    req.session = Session(self.env, req)
  File "/usr/lib/python2.4/site-packages/trac/web/session.py", line 52, in __init__
    self.promote_session(sid)
  File "/usr/lib/python2.4/site-packages/trac/web/session.py", line 147, in promote_session
    (self.req.authname, sid))
  File "/usr/lib/python2.4/site-packages/trac/db/util.py", line 47, in execute
    return self.cursor.execute(sql_escape_percent(sql), args)
  File "/usr/lib/python2.4/site-packages/trac/db/sqlite_backend.py", line 44, in execute
    args or [])
  File "/usr/lib/python2.4/site-packages/trac/db/sqlite_backend.py", line 36, in _rollback_on_error
    return function(self, *args, **kwargs)
OperationalError: columns sid, authenticated, name are not unique

2) Then, I went to Reset Password screen, and entered the name and
   email address. But it showed just "The email and username do not
   match a known account."

3) I backed to "Register an account", and entered my information
   again. But I got the message "Another account with that name
   already exists."

Thank you,
