[Dovecot] Corrupted transaction log

[Paul Warren]

I've just installed dovecot and am trying to use it to access my Maildir
folders.  Unfortunately:

1 SELECT INBOX
1 NO Internal error occurred. Refer to server log for more information.  [2006-12-22 18:06:11]

Log says:

Dec 22 17:55:56 sphinx dovecot: IMAP(pdw): Corrupted transaction log file /home/pdw/Maildir/dovecot.index.log: record size too small (type=0x20, offset=24, size=0)
Dec 22 17:55:57 sphinx dovecot: IMAP(pdw): Unexpected transaction log desync with index /home/pdw/Maildir/dovecot.index
Dec 22 17:55:57 sphinx dovecot: IMAP(pdw): Unexpected transaction log desync with index /home/pdw/Maildir/dovecot.index

Any clues?  Deleting ~/Maildir/dovecot* doesn't seem to help.  I can't
find any documentation relating to the transaction log, or an
explanation of why a fresh install of dovecot might choose to create a
corrupt one.

thanks,

Paul
