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".

I haven't experienced Akregator crashes in a long time (maybe an ocassional crash but not nearly as often as Pekka Korkki reports). Since Fedora 31 is (almost?) EOL I'd be nice to know if this still happens in newer versions of the distro with more up-to-date packages. Otherwise I believe this bug can be closed.

It's ok to close this. I'm on F33 now and don't even remember when I have last experienced this. Sorry I forgot to report this!
