Description:

I recently registered https://bugs.kde.org/show_bug.cgi?id=462326 for kgraphviewer, since it crashes consistently on my system. As can be seen by the later comments, however, my troubleshooting now seem to point in the direction of the Arch Linux package.

Suspiciously enough, manually issuing makepkg for the official PKGBUILD, and installing the resulting package, works. But the package that resides on the official mirror crashes 100% of the time for me when loading the attached file.

Maybe a simple rebuild of the package in a more recent environment (comparable to mine) would be enough? Or maybe there is something in my environment that CMake picks up, and which results in a different, working build?

Additional info:
* kgraphviewer 2.4.3-3
* linux 6.0.9
* plasma 5.26
* wayland

Steps to reproduce:
* Install kgraphviewer
* Start kgraphviewer
* Load the attached file

Yeah, can repro in a fresh Plasma VM. QT stuff can be weird. Even though it makes no sense, sometimes a simple recompile is enough to fix these kinds of inexplicable "issues". Attaching a full backtrace just in case.
