The file is only created to be empty (viper loads the custom-file
whatever I do, so making an empty one seemed the only way to disable it.

I've checked and the error comes from the viper-load-custom-file
function which is calle during load. The file exists according to emacs,
but it cannot be loaded.

Not sure what to test next.
