When pinning icons to the Plasma 6.1.3 Task Manager (i.e. task bar), after a Garbage Collection (NixOS unstable) the icons get corrupted. Both left-click and right-click still work as expected. Left-click will open the respective program and whilst running, the blank icon will be replaced by the correct icon. When the program is closed it returns to a blank icon.
Issue can be mitigated by unpinning then re-pinning the icons, but as this is a regular occurrence this is somewhat annoying.
Steps To Reproduce
Steps to reproduce the behavior:
- In Plasma 6.1.3 pin a few short-cuts to the Task Manager
# Garbage Collection nix.gc = { automatic = true; dates = "weekly"; options = "--delete-older-than 7d"; }; - or
sudo nix-collect-garbage -d

How would I fix this?
That is because for some applications, what KDE Plasma pins is the path to the desktop file in /nix/store, even though it’s accessible in /etc/profiles/per-user/<user>/share/applications or /run/current-system/sw/share/applications. Inspect your .config/plasma-org.kde.plasma.desktop-appletsrc and search for /nix/store, and you’ll find those applications’ desktop files. You can replace file:///nix/store/xxxx/foo.desktop with applications:foo.desktop.

Thanks!
I think it’s a temporary solution.
It would be desirable if KDE Plasma used relative paths or the “applications:” scheme instead of absolute paths.
I have created a script “/home/nixosuser/scripts/fix-plasma-icons.sh”.
mkdir -p /home/nixosuser/scripts
nano /home/nixosuser/scripts/fix-plasma-icons.sh
#!/run/current-system/sw/bin/bash
# Vorherige Pfade anzeigen
echo "Vorherige Pfade:"
grep 'launchers' ~/.config/plasma-org.kde.plasma.desktop-appletsrc
# Pfade in der plasma-org.kde.plasma.desktop-appletsrc Datei ersetzen
sed -i 's|file:///nix/store/[^/]*/share/applications/|applications:|' ~/.config/plasma-org.kde.plasma.desktop-appletsrc
# Spezieller Fall fĂĽr Thunderbird und Firefox
sed -i 's|file:///nix/store/[^/]*/share/applications/thunderbird.desktop|applications:thunderbird.desktop|' ~/.config/plasma-org.kde.plasma.desktop-appletsrc
sed -i 's|file:///nix/store/[^/]*/share/applications/firefox.desktop|applications:firefox.desktop|' ~/.config/plasma-org.kde.plasma.desktop-appletsrc
# Nachherige Pfade anzeigen
echo "Nachherige Pfade:"
grep 'launchers' ~/.config/plasma-org.kde.plasma.desktop-appletsrc
# KDE Plasma neu laden
pkill plasmashell
nohup plasmashell > /dev/null 2>&1 &

It’s highly recommended to give plasma-manager a try. Personally, I use it to declaratively manage all my plasma-related stuff, including panels and applications on the task bar.
