Can also reproduce the crash with the same backtrace.

Arjen, do you see any defects in System Monitor's code here, or is it purely a Qt issue and we should just wait for that patch to be merged? (BTW, thanks Nicolas)
The code actually has a target set so this seems one of those transient state things that definitely shouldn't crash and seems to be purely an upstream issue.

Looks like this it an upstream Qt issue, and it's been fixed with https://codereview.qt-project.org/c/qt/qtdeclarative/+/544750 thanks to Nicolas Fella!

It looks like the cherry-pick to 6.6 did not make it: https://codereview.qt-project.org/c/qt/qtdeclarative/+/550819 Still, this remains an upstream issue so please don't reopen it.

For me, the patch from https://bugs.kde.org/show_bug.cgi?id=482169#c13 was working fine with qt6-declarative 6.6.2. Now, with qt6-declarative 6.6.3 from Kde Neon, i had to apply that patch again and systemmonitor is working fine with Show Details Sidebar.
Still happening on: plasma-systemmonitor-6.0.3-1.fc40 Operating System: Fedora Linux 40 KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.8.4-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-3632QM CPU @ 2.20GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 4000 Manufacturer: Acer Product Name: Aspire V3-571 Reproducible: Always
I updated to Qt 6.7 on neon unstable a few minutes ago; the crash persists. Operating System: KDE neon Unstable Edition KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Graphics Platform: Wayland
Re-opening. :(
Apparently the fix missed 6.70. and it's in 6.7.1. Closing again.

Can Confirm on openSUSE Tumbleweed on Plasma 6.1.2. In particular the crash happens upon selecting an application while the "Show Details" sidebar is already open
Will there be an upgrade of QT to 6.7.1 in KDE Neon?
(In reply to Dm from comment #30) Is it definitely not already? You might want to test Fedora 40, which is on .7.2.
(In reply to Roke Julian Lockhart Beedell from comment #31) > (In reply to Dm from comment #30) > Is it definitely not already? You might want to test Fedora 40, which is on > .7.2. But it's in Fedora, not in Neon (controlled by KDE devs), in Neon QT ver is 6.7.0((
(In reply to Dm from comment #32) Do you ask because you're using it as a personal distribution? It's not designed to be - it's an evaluation one (see https://www.reddit.com/r/linux4noobs/comments/560aah/comment/lexo1z4/). If you're using it merely to evaluate applications, try the Testing, Unstable, or Developer editions available at https://neon.kde.org/download. Remember that although the KDE libraries are rolling, not everything else in the distribution is. It's been a source of pain for a while. Irrespective, might be better to ask questions about library versions in an OS at https://discuss.kde.org/.

USER edition might be better for using as personal distro if kde's dependencies are distributed with all bugfixes (We all are here to make KDE better)
(In reply to Dm from comment #34) Yeah, of course, if the dependencies are up-to-date enough in user. But they don't appear to be. Also, although Qt is more likely than not considered to be a direct dependency, the Ubuntu base is usually quite out-of-date, being LTS.

QT is provided by Neon repo Package: qt6-base Version: 6.7.0-0xneon+22.04+jammy+release+build99 Priority: optional Section: kde Maintainer: Neon CI <neon@kde.org> ... APT-Sources: http://archive.neon.kde.org/user jammy/main amd64 Packages In Fedora QT is 6.7.2 so 6.7.2 could be also in Neon
Yay, Fixed with QT update to 6.7.2 in Neon
(In reply to Dm from comment #37) > Yay, Fixed with QT update to 6.7.2 in Neon Was searching for this bug report. Can confirm, Qt update arrived here on Neon and it's fixed.
