Sentry Crash Report:

Description Anton Borisovich 2024-01-28 22:07:40 UTC 
SUMMARY
kded (5.249.0) crashes if there is a hard disk with a bad SMART state in the system. Apparently it is trying to display a warning that the disk is about to die (although this is not true in my case, but that's not the point). However, if you disable the SMART service in service management, it stops crashing. If you remove a bad SMART hard disk from the system, it stops crashing too.

When it crashes, the console displays the following:
 Registering ":1.161/StatusNotifierItem" to system tray
 ASSERT: "kcm" in file ./src/smartnotifier.cpp, line 43
 KCrash: appFilePath points to nullptr!
 KCrash: Application '<unknown>' crashing... crashRecursionCounter = 2
 Aborted (core dumped)

STEPS TO REPRODUCE
1. Have a disk with bad SMART status in system
2. Start kded6 with "SMART" service enabled in service management
3. crash

OBSERVED RESULT
kded6 crashes silently after some time

EXPECTED RESULT
A new notification would appear that the disk was in a bad state (This is what happens in KDE Plasma 5)
