+Ding persists its settings to $HOME/.dingrc on startup, this sadly includes the path to the dictionary.
+On all other distributions, that would be /usr/share/dict/de-en.txt and would hardly ever change.
+On nixos, this will indeed change on ever update and would break it for all users.
+This just comments out the dictionary path in the .dingrc so the user can still set it if she wants to, but it will not affect normal operations.
