I use disconnected IMAP as a resource for calendar and addressbook. It
has happened now about 3 times where the imap kioslave gets into 100%
cpu, typically after it has noticed a conflict in data even though I
have not edited any event/address. This seems also to happen when I
update an event, then re-update it before it had a chance to sync with
the IMAP server (every 5 minutes or so). Then, it gets into conflict
resolution mode, then IMAP trashing.

The result is then:
- some events/contacts are simply lost
- I have 3000+ empty messages in the corresponding folder (Calendar/ Contacts) all saying "No subject" (once I even had 19000+), which makes the syncing then horribly long.
- I have seen no pattern in the remaining data (like only the oldest, only the first half of the addressbook, etc.)

The data seems to be removed from the IMAP server, as I share this
calendar/contacts with somebody, and their copy gets updated to the
lossy version.

I may do some more operations on this if needed, as we share this on a
"test trial" style.

I can confirm this with the latest kmail1 series, up until now I was not
able to reproduce it on kmail2 but since on kmail2 I can't use IMAP at
all this is rather difficult.

Could somebody else reproduce this with Kmail2? Changed severity to
"Very high" as it involves data loss on the IMAP server
