Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.2-ck1 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

Akregator crashes the moment the window is closed each time.  The downloaded
articles are not kept and akregator starts again as if not run the previous
time.

The crash can be reproduced every time.
