Same happens to me on a fresh install. Seems like this bug should have higher importance as it provides a very easy way for new users to accidentally "completely break" their system and the only way to get back in requires manipulating files in text mode (not ideal for someone who just switched to Linux). Definitely at least remove the file until it stops causing trouble.
