Crash log from journalctl

SUMMARY
Spotify video player apparently causes KDE to crash. This problem is recent and hasn't been present on Plasma version 5.


STEPS TO REPRODUCE
1. Use KDE Desktop
2. Use Spotify (from the spotify-launcher package on arch linux) and play a music video

OBSERVED RESULT
Desktop wallpaper disappears, so does the desktop menu. A crash can be observed in journalctl.

EXPECTED RESULT
No Crash

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux, Package version 6.0.2-3
(available in About System)
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 
- plasma-framework5 5.115.0-3 (kf5)
- frameworkintegration 6.0.0-1 (kf6)

Please provide a full backtrace from coredumpctl gdb

Comment 3 ian.rehwinkel 2024-03-17 15:03:55 UTC

This is from kded6. It seems to be the same as Nicolas Fella posted. The other threads seem to be waiting on some condition variables and likely have no interesting backtrace:
