KMail Version 4.8.5: After downloading the emails from the server and switching to the local inbox folder KMail crashed. After restart everything works fine again. This bug might appear after booting the computer but it is rare.

Sorry it's a very old version. And crash is in soprano that we don't use now. So I close as wontfix. Sorry. Better to upgrade version. Regards
