OK - there are two spots in the code that can produce exactly that
error message.  One is in BDB, which I assume you're not using.  The
other is in mboxlist (latest CVS changes this one to "error fetching
mboxlist user.[username]: [error]" to be clearer!)

So, it's in mboxlist_mylookup.  The specific error is being returned
by:

    if (wrlock) {
        r = DB->fetchlock(mbdb, name, namelen, &data, &datalen, tid);
    } else {
        r = DB->fetch(mbdb, name, namelen, &data, &datalen, tid);
    }

    ...
    
    default:
        syslog(LOG_ERR, "DBERROR: error fetching mboxlist %s: %s",
               name, cyrusdb_strerror(r));
        return IMAP_IOERROR;
        break;

Sorry I didn't get back to you before.  I really don't think I can
debug this any further without a copy of your mailboxes.db file.

I assume you've ruled out filesystem corruption by checking syslog/dmesg/
whatever for signs of bad blocks?
