Bug ID: 380469
Summary: Plasma crashes when closing grouped kwrite windows at
once
Product: plasmashell
Version: 5.8.6
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ouissalbenam...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.8.6)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.62-18.6-default x86_64
Distribution: "openSUSE Leap 42.2"
-- Information about the crash:
- What I was doing when the application crashed:
I had multiple Kwrite windows open (they were grouped, and over 5 windows), so
when I right clicked and clicked on "close" to close them all, plasma crushed.
It happened twice now.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
