Bug 371531

Application: akregator (5.2.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-26-generic x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
On Kubuntu 16.10, Akregator crashes on exit almost every time. I'm not 100% sure, but I think that it doesn't crash if I just start it and then exit. If I read any articles before exiting, it crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
