[Dovecot] Problem with manually moving maildir files between folders

[Bill Landry]

dovecot --version
1.1.beta1

With previous versions of Dovecot I could manually move maildir files
between folders and the index would automatically update when entering
the folder with Thunderbird.  However, with 1.1.beta1, I am seeing the
following when entering the folder, when attempting to rebuild the
indexes via Thunderbird, or when attempting to force the download of all
messages in the folder (this is with mail_debug = yes):

I'm not sure where the "server log" is that the last line above is
referring to.  Here is my running config:

dovecot -n

Let me know if there is additional info that is needed.
