gdb full backtrace

I'm having the same issue and I can reproduce it consistently.

Keep in mind that I'm running Plasma on Wayland using NVIDIA's proprietary graphics driver, version 440.82.

Operating System: openSUSE Tumbleweed 20200611
KDE Plasma Version: 5.19.0
KDE Frameworks Version: 5.70.0
Qt Version: 5.15.0
Kernel Version: 5.6.14-1-default
OS Type: 64-bit
Processors: 4 × Intel® Core™ i5-3570K CPU @ 3.40GHz
Memory: 7,7 GiB of RAM
Graphics Processor: GeForce GTX 660/PCIe/SSE2
Comment 2 Guilherme Silva 2020-06-13 06:11:25 UTC 
Hmm, now that I think about it, I think my issue might not exactly be related to yours...

Once I select the theme and hit "Apply", my screen goes completely dark. Though I'm able to switch to a VT, I don't know how to end that Plasma session that is broken, so I just restart my computer instead.

Also, according to coredumpctl, is plasmashell that crashes for me, not kwin_wayland:

$ coredumpctl list --since=today

Comment 3 Patrick Silva 2020-06-13 11:08:46 UTC 
plasma crash was reported as bug 414834
Comment 4 Guilherme Silva 2020-06-13 18:19:02 UTC 
Thanks, I'll post it there.

Comment 6 Patrick Silva 2020-10-05 16:27:13 UTC 
Sometimes Plasma loses its settings (icons arrangement/alingment, wallpaper and widgets) after this crash.

*** Bug 428690 has been marked as a duplicate of this bug. ***
Comment 8 Carl Schwan 2020-11-18 14:22:54 UTC 
For me, it crashes the entire section each time. I tried changing the individual appearance settings individually and this works fine.

Plasma 5.20.80
KDE Framework master
Qt 5.15.1

Comment 10 Patrick Silva 2021-03-30 11:04:25 UTC 
This crash is still happening on non unstable.

Comment 11 Nate Graham 2021-03-30 18:48:47 UTC 
Your backtrace is in QtWaylandServer::org_kde_kwin_blur_manager::bind_func which is different from the one originally reported. Seems like Bug 435009 is related. Re-closing this the original issue here is fixed. Please file a new bug report for the new crash. Thanks!
