There are two imap accounts and one pop account configured in kmail. If I first check the new mails in a Imap account  and then try to view the new mails in the POP account, kmail crashes. However if I first open the POP account, there is no problem to view the mails. Crashlog:
Anwendung: KMail (kmail), Signal SIGSEGV
