            Bug ID: 342731
           Summary: Kontact crashes when switching from KMail to Akregator
           Product: kontact
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: s.heimbach at explosive-software.de

Application: kontact (4.14.3)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Was using KMail/Kontakt and switched to Akregator/Kontakt. After a few seconds
(maybe looking for new feeds) Kontakt crashes.

This does *not* happen when I open Akregator as stand-alone.

The crash can be reproduced every time.

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