            Bug ID: 310025
          Severity: crash
           Version: 4.9.3
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Kmail crashing when started
    Classification: Unclassified
                OS: Linux
          Reporter: greve at fsfe.org
          Hardware: Fedora RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kmail2

Application: kmail (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.6.6-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I stared Kmail.

Suspect this is triggered by Akonadi issues, as MySQL dies underneath Akonadi
regularly. But then Kmail should then simply tell the user that Akonadi does
not work, it should defintely not segfault.

The crash can be reproduced every time.

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