In this case, the truth is in the traceback.

Here is the relevant part of the pysvn documentation:
http://pysvn.tigris.org/docs/pysvn_prog_ref.html#pysvn_client_callback_get_login

pysvn.Client seems to require that you declare a callback function to
provide login credentials when needed to access a repository/project, if
not previously cached (or if caching is disabled). A simple example
providing a callback function might look like this:

def login(*args):
    return True, 'myuser', 'mypass', False

import pysvn
client = pysvn.Client()
client.callback_get_login = login
client.checkout('http://subversion.example.com/someproject/trunk')

But, the above might not be acceptable -- depending on security
concerns, as your repository password is presented in plain text.

HTH,
Marty
