Description Roke Julian Lockhart Beedell 2025-07-05 16:12:26 UTC 
Application: plasmashell (6.4.1)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.15.0
Operating System: Linux 6.15.4-200.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.4.1 [CoredumpBackend]

-- Information about the crash:
Per https://bugzilla.redhat.com/show_bug.cgi?id=2376516, at the "Quick Settings" page, [^1] I attempted to switch global theme from `org.kde.breezedark.desktop` to `org.kde.breeze.desktop` (like `lookandfeel --apply` would). Although I *believe* that I hit "Apply", after which the theme changed, *then* the window decoration's closure button. When I did, "Apply Settings" modal window appeared regardless. When I selected "Apply", the window closed, and the theme reverted, for the applications, but didn't for the shell. After 0.75s, the shell crashed and automatically reloaded, whereupon Dr Konqi and GNOME Abrt invoked.

[^1]: https://discuss.kde.org/t/which-kcm-maps-to-quick-settings-does-one/36650?u=rokejulianlockhart

The crash does not seem to be reproducible.

https://bugzilla.redhat.com/show_bug.cgi?id=2376518 occurred soon enough afterward that I'll add it too.

Comment 5 Roke Julian Lockhart Beedell 2025-07-05 20:43:41 UTC 
I should have included my environment:

> ~~~
> Operating System: Fedora Linux 42
> KDE Plasma Version: 6.4.1
> KDE Frameworks Version: 6.15.0
> Qt Version: 6.9.1
> Kernel Version: 6.15.4-200.fc42.x86_64 (64-bit)
> Graphics Platform: Wayland
> Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor
> Memory: 32 GiB of RAM (30.4 GiB usable)
> Graphics Processor 1: AMD Radeon RX 5700
> Graphics Processor 2: AMD Radeon Graphics
> Manufacturer: ASRock
> Product Name: X670E Taichi
> ~~~

...since, per https://bugs.kde.org/show_bug.cgi?id=506652, this also reproduces on my laptop. That issue also explains what I believe to be the cause of this bug, although it's not yet reproducible enough for certainty.

Comment 7 TraceyC 2025-07-09 19:04:33 UTC 
This backtrace is nearly identical to bug 500565, which we thought was fixed in 6.3.2
Comment 8 Roke Julian Lockhart Beedell 2025-07-09 19:13:26 UTC 
(In reply to TraceyC from comment #7)

I believe that I've been unable to reproduce it since, so it might occur solely once per installation. My assumption earlier that decided the current title might not be accurate.

So we're refreshing the icon theme, and we ask for the name of the current icon theme, which goes through KConfig, which looks at an INI-style config file, and tries to parse it, and blows up in Qt code.

Could be a timing issue where the config file gets updated atomically and KConfig tries to read it in the unfortunate moment when it's in a transitional state.

I've seen this too on Tumbleweed with Plasma 6.4.4, Frameworks 6.17.0 and Qt 6.9.2, when switching between Breeze and Breeze Dark in Quick Settings:

I was able to trigger the "Apply" popup dialog after switching themes, but plasmashell did not crash on Neon Testing with Plasma 6.4.4
Given that this is likely a timing issue that doesn't prove much. I'll mark this confirmed since more than one person reproduced
