Thunderbird unread message count

[Dr. Michael J. Chudobiak]

Has anyone else had problems with Thunderbird showing incorrect 
unread-message counts on IMAP folders since the last TB update (in the 
past week or so)?

I don't see any bugs reported on it in the Fedora bugzilla.

I'm using dovecot as the IMAP server.

Deleting the TB *.msf files on the client, and the dovecot* index files 
on the server, did not help.

dovecot-2.2.5-1.fc19.x86_64
