db errors at every startup

[Anders Norrbring]

At every startup of Cyrus-IMAP, I get the following in my logs:

Specifically I'm worried about the lines "DBERROR: archive 
/var/lib/imap/db: cyrusdb error"..

I've tried with both db_recover and Cyrus' recontruct, but the error 
lines are there anyway.

Any advice on this please?
