Additional context
Had a look into the log files before the update - the value behind the log entries STATUS INBOX is always something cryptic like "`�li4V".

Maybe commit b7963eb has something to do with it?

MailSo IMAP parser converts '(....)' into an array. This should be fixed now.

Can confirm that SnappyMail works again 👍. Thanks a lot!
