Bug ID: 376550
Summary: akregator crashes on use
Product: akregator
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-b...@kde.org
Reporter: spac...@gmail.com
Target Milestone: ---
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".
