[Dovecot] More AFS maildir debugging

[Aaron Solochek]

There appears to be some sort of a race condition when accessing a maildir 
directory for the first time with dovecot.  I was getting a non-specific error 
trying to select INBOX, but when I stepped through it with a debugger it worked. 
  Deleting the dovecot files and running the select again it failed.  I started 
playing with it again just now, and when attempting to access Sent, I actually 
got some errors:

a04 select Sent

imap(aarons): Error: Corrupted transaction log file 
/XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header

imap(aarons): Error: Corrupted transaction log file 
/XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header

imap(aarons): Error: Corrupted transaction log file 
/XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header

a04 NO Internal error occurred. Refer to server log for more information.

I then deleted dovecot.index.log and dovecot.index.log.2 (the only two dovecot 
files that were present) and retried the select:

a04 select Sent

a04 NO Internal error occurred. Refer to server log for more information.

Does anyone more familiar with the code than myself have any pointers of where 
to concentrate my debugging efforts?

Thanks.
