Summary: kded6 crashes when printing, causing system tray icons
to disappear
Classification: Frameworks and Libraries
Product: frameworks-kded
Version First 6.24.0
Reported In:

Full stacktrace
SUMMARY
When printing a PDF, the kded6 crashes with a SIGSEGV. kded6 restarts
automatically, but not all system tray icons are restored afterwards. The print
job itself completes successfully.
STEPS TO REPRODUCE
1. Open a PDF (e.g. in Okular or any PDF viewer).
2. Print the PDF via File → Print.
3. Observe: print job completes successfully, but kded6 crashes immediately
after.
OBSERVED RESULT
kded6 terminates with signal 11 (SIGSEGV). KDE automatically restarts
kded6, but not all system tray icons are restored after the restart —
some icons remain missing from the panel until the affected applications
are restarted manually.
EXPECTED RESULT
Printing completes without crashing kded6. System tray icons remain
visible and functional after printing.
