first_list/middle_list/last_list are plain public attributes (not properties), so they can be assigned directly, bypassing parse_pieces's whitespace normalization. If an assigned element contains an internal double space, _process_initial (parser.py:269, initials.append(part[0])) crashes with IndexError: string index out of range, because "".split(" ") yields an empty string for the collapsed gap.
Repro:
from nameparser import HumanName
n = HumanName(first='John')
n.middle_list = ['Q R'] # double space inside one list element
n.initials_list() # IndexError: string index out of range
Going through the normal constructor/property paths is safe (HumanName("John Q Doe") or first="A B") since those go through parse_pieces, which normalizes whitespace. The crash only happens via direct assignment to the *_list attributes.
Found while reviewing #229 / PR #231 — unrelated to that cleanup; it's a pre-existing issue.
