-- Information about the crash:
The Plasma crashed when Kontact was closed.  BTW, the KMail in Kontact has a lot to improve, it's hard to configure and add email accounts in the KMail than Thunderbird client and many times an email account just doesn't work such as retrieve mails in the KMail even if it's set up with the same configuration as it's in Thunderbird or other email client.

The crash can be reproduced some of the time.
