Yes, almost certainly a 2.4 bug.  We had another bug which was even
worse that we managed to roll out at FastMail just last week for a
few hours (a code cleanup that introduced a subtle difference in
behaviour).  It also affected Mac clients, because I think they use
the LIST "" "" and LIST "" user commands instead of the NAMESPACE
command like a lot of other clients.

I've filed a bug for you.
