Bug ID: 462217
Summary: KRunner crashes if the current LookAndFeelPackage
doesn't exist
Classification: Plasma
Product: krunner
Version: 5.25.5
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: ferenos...@outlook.com
CC: alexander.loh...@gmx.de
Target Milestone: ---
Application: krunner (5.25.5)
(Compiled from sources)
Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.4.0-132-generic x86_64
Windowing System: X11
Distribution: Feren OS
DrKonqi: 5.25.5 [CoredumpBackend]
-- Information about the crash:
KRunner crashes if kdeglobals's KDE/LookAndFeelPackage value is set to the ID
of a Global Theme that doesn't actually exist. Setting it to one that does
exist immediately fixes the crashes, and while in the non-existent-Global-Theme
state restarting KRunner from DrKonqi can yield the same bug that was reported
in bug report 447113 on the rare occassion.
ksplashqml also crashes if its theme value in ksplashrc is set to a
non-existent Global Theme ID, too, just for an additional note.
The crash can be reproduced every time.
-- Backtrace:
Application: KRunner (krunner), signal: Segmentation fault
