Bug ID: 423098
Summary: Random okular crashing when focused.
Product: okular
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: okular-devel@kde.org
Reporter: chhajedchin...@gmail.com
Target Milestone: ---
Application: okular (1.10.0)
Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-37-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I wasn't doing anything in okular and I was in other window. When I focused
screen on which okular was open, it automatically closed. This happens every
time after I added this ppa `sudo add-apt-repository
ppa:kubuntu-ppa/backports`. I use dwm tiling window manager and not default KDE
Plasma. I have updated my kubuntu to 20.04 and since then many KDE applications
(eg: `systemsettings5`) are failing to open. Okular wasn't one of them but when
I added this ppa, it started to crash.
- Custom settings of the application:
The crash can be reproduced every time.
-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
