P1: Critical Description
On NixOS unstable (KDE plasma 5.27.3, qt 5.15.8), but also on NixOS 22.11 (KDE plasma 5.26.5, qt 5.15.7), executing `plasmashell -v` outputs the name of the program and the version, but then segfaults.
As a comparison, executing `kbroadcastnotification -v`, gives a similar output but does not segfault.
Please also see the issue reported at KDE https://bugs.kde.org/show_bug.cgi?id=467696 and the issue reported on the nix repo https://github.com/NixOS/nixpkgs/issues/220168
The segfault seem to be the cause for an issue on latte-dock https://github.com/NixOS/nixpkgs/issues/212828
Here is the relevant backtrace:
