Unlimited number of values causes fatal error when editing node

When I try to set up an "unlimited" files field, it actually died with a fatal error. That's why I am setting the priority as "Critical".

But, I have a very easy fix. I fixed it by editing encrypted_files.module, line 155 - 159, make it look like this:

  foreach ($element as $key => $item) {
    if (is_numeric($key)) {
      $element[$key]['#upload_validators']['encrypted_files_validate_encrypt_config'] = array($context['field']['settings']['encrypt_config']);
    }
  }

What's happening is it's testing to make sure the $key is numeric before proceeding. That's all you need to do.
