Hello,
I'm trying to migrate dovecot mail database from 2.0.9 on Linux to 2.3.20 on FreeBSD. I've rsync'd the entire database, grabbed all the configs, changed the paths and permission, but when trying to access the mail from Thunderbird I have reproducible crash in the logs:

There's an older thread here mentioning that probably doveadm force-resync would help, but it doesn't fix this. Is there something that could be done here ?
I've also reported this in the FreeBSD bugtracker, but just in case decided to ask here too.
