dovecot - Apr 2008 - Broken Debian package

Hi,

I have run Dovecot via Debian for some years but in the last few weeks
something has broken....I have been upgrading Debian but today rebooted it
to try and sort out a failed DLT....now I find dovecot is non-functional....

So,

Where to look for faults please? ie logs? can I make dovecot verbose?
Thunderbird if telling me Dovecot is not imap4 compliant........and I cannot
connect to it...

I have tried re-installing Dovecot but the Debian package contains no
dovecot.conf....so I have dovecot imap-d and dovecot common installed but no
config.

So I copied back the config files from a safe location....

When I start up I get,
hermes:/var/log# tail dovecot
dovecot: 2008-04-06 11:32:32 Info: Dovecot v1.0.rc15 starting up
hermes:/var/log#

So trying to connect, tail -f (on /var/log/dovecot),

Gosh, what a mess.

So it's aborting probably with some assertion violation.

Can you use the Dovecot from backports.org?  It's way more recent. 
backports.org packages are also prepared by Debian developers.
