Jaguar Mail.app (using GSSAPI) thrashes with cyrus imap 2.1.9

Since upgrading our cyrus imap server from 2.0.16 to 2.1.9 the MacOSX
Jaguar Mail.app no longer works with GSSAPI authentication.

The cyrus server logs a successful GSSAPI authentication for a user, but
Mail.app then violently spins it's wheels while performing two tasks:

    "Traversing mail hierarchy"
    "Fetching headers"

tcpdump running on our cyrus server captures over *8000* imap packets
going back and forth to the Jaguar Mail.app.  Finally Mail.app "quits
unexpectedly".

The cyrus server is running on a RedHat 7.3 system using rebuilt
versions of Simon Matter's SRPMs.

Before the upgrade to cyrus 2.1.9 the Jaguar Mail.app was quite happy to do
GSSAPI authentication to the cyrus server.  And, in fact it still does a
fine job connecting with GSSAPI to a UW imap server.

Here's the kicker... If I change the config on Mail.app and have it
authenticate PLAIN over SSL then everything works without a hitch!

Has anyone else seen this problem?  

I don't see any mention of it on the info-cyrus archives.

P.S.  The following other imap clients are doing GSSAPI authenticated
connections on multiple plaforms without any trouble at all:

    mutt-1.4
    mullberry-2.x
    mullberry-3.x
    pine-4.33
    pine-4.44
