[issue22319] mailbox.MH chokes on directories without .mh_sequences

[Tim Chase]

Tim Chase added the comment:

I had to tweak the example reproduction code as it seemed to succeed (i.e., fail to demonstrate the problem) in some instances.  The same exception occurs, but here's the full original traceback:


$ cd /home/tim/.claws-mail/imapcache/mail.example.com/tim at example.com/INBOX/
