            Bug ID: 342879
           Summary: Crashes out of the blue
           Product: kmail2
           Version: 4.14.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: fabian at ritter-vogt.de

While doing absolutely nothing with KMail, it's just running in the background,
the crash handler dialog appears. This happens multiple times a day, sometimes
not once a week. I don't know how to reproduce. Akonadi is still running fine.

Reproducible: Sometimes
