How to reproduce:

1. Start Final Fantasy XIV via launcher
2. Immediately exit the game in the main menu
3. At exit, the character specific configuration files are corrupted +
FFXIV.cfg is empty.

This issue started with commit 7da7ae7. It works fine before that. I've already
notified Zebediah Figura about this but I still think it's important to do a
proper bug report.

Please tell me if you need more information.
