If I quit my kde session kontact crashes 80% of the time. It might actually be kmail, since after the crash the pop3 account's server/username/password are gone.

Since I am not sure how to reproduce I can just state what I do. Basically kontact opens during session restore with kmail as active component. It checks for mail, there is no new mail retrieved, I click on "check mail" and leave it minimised or opened while logging out. I'll have to try a few times to check whether minimised to tray changes something.
