Application: akregator (5.5.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.10.0-26-generic x86_64
Distribution: KDE neon User Edition 5.10

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

Akregator is behaving weirdly recently in my up-to-date KDE neon User Edition. Shortcuts sometimes work sometimes does not. Feeds appear as unread even though they are marked as read manually, etc. This was all with embedded Akregator in Kontact.

I decided to give Akregator a try as standalone application. Akregator launches right but as soon as I click on anything it crashes. This happens everytime.

The crash can be reproduced every time.

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