            Bug ID: 364000
           Summary: Akregator crashes during start
           Product: akregator
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: gabriel at rueeck.de

Application: akregator (4.14.10)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-35-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
When I start Akregator, it crashes. If I repeat the action, the same behaviour
persists.
- Custom settings of the application:
If I start kontact and then click on Akregator, it works. But as stand-alone,
it does not work.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
