[Dovecot] 1.0rc29: Corrupted index cache file

[Jeff Rice]

Hi,
I have recently migrated from Courier to Dovecot, and I noticed a 
problem in one of my spam scripts.  Here's the setup:

Spam that needs to be retrained by the filter is placed in a maildir 
from the IMAP client.  A cron job scans that maildir and if it finds a 
message, feeds it to the spam filter and removes it from the training 
maildir.  Depending on whether or not the message was a spam or ham, it 
is either deleted or delivered to Inbox.

It appears I am getting an error when the script deletes a mail message. 
  I haven't checked if this message only occurs when a client is 
connected -- it's possible.

Log excerpt:
