Bug ID: 402784
Summary: Dolphin crashes during shutdown, when stopping
activity
Product: dolphin
Version: 18.12.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: simon.pers...@mykolab.com
CC: elvis.angelac...@kde.org
Target Milestone: ---
Application: dolphin (18.12.0)
Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.8-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
How to reproduce:
Press Win+Q, make sure that you have two plasma activities running. Start
dolphin in current activity. Press Win+Q again and stop current activity.
Dolphin crashes while it is stopping. It does not matter if you have another
instance of dolphin running in the other activity.
In the backtrace it looks suspicious that there is a recursive call to the
destructor of KItemListViewAccessible.
The crash can be reproduced every time.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
