Trac migrate from sqlite to mysql

I'm trying to migrate our trac database from sqlite to mysql using the TracMigratePlugin (http://ift.tt/1BxQkkO) but I get the following error:

  File "plugins/tracmigrateplugin/trac-migrate.py", line 55, in <module>
    sys.exit(main(sys.argv[1:]) or 0)
  File "plugins/tracmigrateplugin/trac-migrate.py", line 51, in main
    return TracMigrationCommand(env)._do_migrate(dest, dburi)
  File "/var/lib/stej/plugins/tracmigrateplugin/tracmigrate/admin.py", line 36, in _do_migrate
    return self._do_migrate_to_env(env_path, dburi)

Running trac 1.0.1 on debian wheezy, I get the error when running the following command:
