Python & RA

I've been trying to use python to use Subversions Remote Access library, but it crashes.

#!/usr/bin/python

import os
import svn
import svn.ra
import svn.client
import svn.core

svn.ra.initialize()

class Callbacks(svn.ra.Callbacks):
    def __init__(self):
        self.auth_baton = svn.core.svn_auth_open([
            svn.client.get_simple_provider(),
            svn.client.get_username_provider(),
            ])
        svn.core.svn_auth_set_parameter(self.auth_baton,
                                        svn.core.SVN_AUTH_PARAM_DEFAULT_USERNAME,
                                        "eggert")
        svn.core.svn_auth_set_parameter(self.auth_baton,
                                        svn.core.SVN_AUTH_PARAM_DEFAULT_PASSWORD,
                                        "aaa")
    def open_tmp_file(self, pool):
        path = '/tmp/'
        (fd, fn) = tempfile.mkstemp(dir=path)
        os.close(fd)
        return fn
    def cancel_func(self):
        if False:
            return svn.core.SVN_ERR_CANCELLED
        return 0

c = Callbacks()
svn.ra.open2("http:/svn.example.com/svn", c, {})

My backtace looks like this:
