mailbox list with / delimiter gives error on recursive processing

[x-m-nc]

I tryed to deduplicate mails on my mailbox (dont know the kind of server)

I got a list of mailboxes just fine
INBOX
INBOX/subfolder
INBOX/subfolder/subfolder and so on

with the option -r it wont process:

"Traceback (most recent call last):
File "./imapdedup.py", line 535, in
main(sys.argv[1:])
File "./imapdedup.py", line 531, in main
process(options, mboxes)
File "./imapdedup.py", line 396, in process
for mb in get_mailbox_list(server, parent, pattern):
File "./imapdedup.py", line 257, in get_mailbox_list
bits = parse_list_response(mb)
File "./imapdedup.py", line 165, in parse_list_response
m = list_response_pattern.match(line)
TypeError: expected string or bytes-like object"

-> Probably the delimiter of folders is the problem?! . vs / ?

Similar problem here when running against Apple iCloud Mail:

+ python3 imapdedup.py --server imap.mail.me.com --port 993 --ssl --user xxx --password xxx --verbose --show --dry-run --checksum --recursive INBOX
Traceback (most recent call last):
  File "imapdedup.py", line 598, in <module>
    process(options, mboxes)
  File "imapdedup.py", line 445, in process
    delimiter = bits[1].decode()
TypeError: 'NoneType' object is not subscriptable

… but only with the --recursive option specified.
