            Bug ID: 415902
           Summary: Akregator crashes when opening a post
           Product: akregator
           Version: 5.11.3
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: pekka.korkki at gmail.com
  Target Milestone: ---

Application: akregator (5.11.3)

Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.16-300.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

-- Information about the crash:
I'm on a fresh installation of Fedora 31 KDE Spin. Akregator has been very
crash-prone since the installation and after all the updates that have arrived
so far. The current version of Akregator on my system is 5.11.3.

The crashes seem to happen when I move to an unread feed or post. I usually use
the keyboard shortcuts for navigation but I doubt it's relevant since I have
been able to replicate this even when using the trackpad.

I know of at least one occasion where Akregator just crashed on it's own
without me doing anything in it at the time.

The crash can be reproduced sometimes.

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