Sentry Crash Report:

Description The Feren OS Dev 2022-11-24 21:08:06 UTC 
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

Comment 1 Bug Janitor Service 2022-11-24 21:33:30 UTC 
Thank you for the bug report!

Please note that Plasma 5.25.5 is not supported for much longer by KDE; supported versions are 5.24, and 5.26 or newer.

If at all possible please upgrade to a supported version and verify that the bug is still happening there.

If you're unsure how to do this, contact your distributor about it.
Comment 2 Nate Graham 2022-11-30 04:21:01 UTC 
This was fixed in Plasma 5.26 where loading files from the current theme for KRunner was removed.
