Bug ID: 373517
Summary: System Settings crash when removing custom keys
Product: systemsettings
Version: 5.8.4
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: tankta...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.8.4)
(Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.28.0
Operating System: Linux 4.8.12-gentoo-r1 x86_64
Distribution: "NAME=Gentoo"
-- Information about the crash:
- What I was doing when the application crashed:
I'm trying to set custom keys for Amarok's Play/Pause action, and I get this
regularly when attempting to remove an old setting. Turns out that when I
restart system settings and return to the global shortcuts to try again, the
removal is registered there. (I'm also unsuccessful at getting Amarok to
play/pause with the shortcut chosen).
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
