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".
