Ok. Thanks for the confirmation.

I looked there this morning, as far as I remember there was nothing
shown for that folder. Following advice I got from the kdepim-user list
I then cleared the akonadi cache for said folder, which on restart of
KMail eliminated the ghost messages. So I cannot say for sure what was
there before.

I will keep that in mind.

My first suspect would be a folder with an expiration policy that was
due to delete about 3000 messages and failed to do so.

I also had some crashes of the akonadi imap resource handler that
happend nearly every night for the last week or so (not today, though).

I will keep an eye on this.

I sadly do not know what that means...
