I'm using KolabDroid to sync my telephone with the imap server via a TLS connection. I enter a new contact on the phone. KolabDroid makes the appropriate entry on the imap server. Kolab produces the error message noted in the title and no entry appears in Kontact.
This looks like a generic imap/akonadi problem. You could try to run 'akonadictl fsck' (which is completely unsafe and will probably delete all your data, so at your own risk ;-). If you still think it is because of kolab, you'll have to send me a mime message of a problem-causing item.
