Bug ID: 415107
Summary: Kwin crashes when launching Rainlendar
Product: kwin
Version: 5.14.0
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: gijsb...@rondte.nl
Target Milestone: ---
Application: kwin_x11 (5.14.0)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-72-generic x86_64
Distribution: Ubuntu 16.04.6 LTS
-- Information about the crash:
- What I was doing when the application crashed: just launched Rainlendar2
(2.14.3 - beta)
Apart from that various other applications were open: Firefox, Vivaldi, Deezer
(on Nuvola app), Telegram Desktop, Thunderbird.
Nothing else was done, but launching Rainlendar, which was just installed from
.deb file.
The same happened when launching Rainlendar 2.15 just after having installed it
the other day.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
