I tried recreating this by moving my Ubuntu.mirrors file aside e.g.: sudo mv /usr/share/python-apt/templates/Ubuntu.mirrors /tmp/
and that did not cause a crash but raised an error message saying to check your Internet connection. Then after closing the mirror selection dialog box I received the following Traceback.
