Description Spacial 2017-02-16 15:13:49 UTC

Application: akregator (5.3.3 (QtWebEngine))

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.8-201.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

-- Information about the crash:
- What I was doing when the application crashed:
just opened, asked to sync my feeds and was reading one news, then it crashes suddenly.

tried 3 times in a rows.

(some 4 months ago, the http.io thread - on kde overall - was stuck with 100% CPU trashing the system - consuming all memory and cpu time.)

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
