            Bug ID: 369035
           Summary: KMail crashes randomly
           Product: kmail2
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: bugs.kde.org-1 at gcth.net

Application: kmail (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.4.19-1-default x86_64
Distribution: "openSUSE Leap 42.2 Beta"

-- Information about the crash:
These are quite hard to reproduce - sometimes kmail crashes after several hours
of work, sometimes (more often) fails to start at all and requires several
attempts. I'm using KDE software from the following repository:
https://build.opensuse.org/project/show/KDE:Applications

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
