Hi all,

I think I've been bitten by the same bug. My situation: dimap with around 20k 
items, of which 3k in the subfolder used for the calendar. I use kontact 
(with embedded kmail and korganizer), korgac and kpilot. I have used kontact 
on another machine sometimes with the same imap account, but not lately.

The trouble started when kmail complained about a calendar entry that differed 
between the cached version and the version on the server. It asked me what to 
do. I thought I had edited the entry on the other machine, and told kmail to 
keep both versions for all future conflicts. That was a mistake. 

After a while, kmail seemed to be locked up. Eventually, I killed the process. 
After that, kmail never came back up properly. I looked in the maildir on my 
imap server, and found two kinds of erroneous items:
1. around 6500 messages containing only the text:
	X-UID: 0
	Status: RO
	X-Status: OC
	X-KMail-EncryptionState:
	X-KMail-SignatureState:
	X-KMail-MDN-Sent:
2. around 12600 copies of a single appointment from my calendar, each with 
their own message ID, and with a summary with varying number of "copy of: " 
prepended to it. If anyone is interested, I'll send a sample of the 
duplicated by private mail.

After moving both types out of the way, kontact worked properly again.

Since then, I've had the question about conflicting calendar items one more 
time. This was just after a kpilot crash while it was syncing to my Palm. I 
do not remember whether that was also the case the previous time. I told it 
to use the most recent version, and that seems to work. 

Any ideas how to prevent this kind of trouble, which seems unrecoverable 
without access to the imap server (like I had, luckily)?

Cheers

Jan-Pascal
