File path and file name cleanup settings do not get stored when using Upload module

I'm using the core Upload module and I've run into an issue with the FileField Paths' file path and file name cleanup settings not being stored after submitting the content type editing form. No matter what checkboxes I set ("Cleanup using Pathauto", "Convert to lower case"), they just wouldn't stick.

It appears that the issue was caused by improper referencing into the $form_values array in filefield_paths_form_submit(). The patch, sponsored by http://rockpeaks.com, is attached.
