built-in Dream Skin theme cannot be deleted

Error message

built-in Dream Skin theme cannot be deleted

What it means

Guard in delete_dream_skin_theme: the target theme directory is not a regular directory (symlink or special file), so deleting it could remove something outside the themes root. Deletion is refused as a path-safety measure.
