Description Alireza Rashidi 2024-10-18 16:52:40 UTC 
Application: plasmashell (6.2.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.7.3
Frameworks Version: 6.6.0
Operating System: Linux 6.11.3-zen1-1-zen x86_64
Windowing System: Wayland

-- Information about the crash:
I am experiencing a recurring issue with KDE Plasma where the entire desktop environment crashes and restarts every time I attempt to change the wallpaper type in the background settings.

Steps to Reproduce:
- Open "Desktop and Wallpaper" settings.
- Change the wallpaper type (e.g., from "Image" to "Slideshow").
- Observe that KDE Plasma crashes and restarts.

Additional Information:
I suspect that this issue may be related to my current settings or installed plugins, as I tested with a new user account and did not encounter the same problem.

Please let me know if you need any further information to assist in resolving this issue.
Thanks!

The crash can be reproduced every time.

Comment 3 Nate Graham 2024-12-12 20:04:51 UTC 
It would appear that someone is using DBus wrong:

#10 0x000071a33d3f88eb in _dbus_warn_check_failed (format=0x71a33d402b20 "Array or variant type requires that type %s be written, but %s was written.\nThe overall signature expected here was '%s' and we are on byte %d of that signature.") at /usr/src/debug/dbus/dbus-1.14.10/dbus/dbus-internals.c:289

What 3rd-party plugins or add-ons have you got installed? It'll probably be one of them. Once you figure out which one, it would be great to report this to its developer.
