crashes. If no external zip-utility is found, the archive is created by the zipfile module, which behaves different now than in 2.1: if the zip-file is created in the root directory if the distribution, it will contain an (empty) version of itself. This triggered the above bug - so it's better to create the zip-file far away in the TMP directory.
