            Bug ID: 383826
           Summary: akregator chrashes on opening first feed on first
                    startup
           Product: akregator
           Version: 5.5.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: marcus at jet.franken.de
  Target Milestone: ---

Application: akregator (5.5.3)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

After freshly booting, opening Akregator and then selecting the first feed
will crash akregator immediately.

Starting it a second will make it work, but then the feeds are not fetching.

The crash can be reproduced every time.

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