			=== Plasma wallpaper reverts back to default after a Nix GC ===
			When setting a wallpaper, Plasma may save the path as a <code>/nix/store/*/share/wallpapers</code> path instead of <code>/run/current-system/sw/share/wallpapers/</code>. To fix this, open <code>$XDG_CONFIG_HOME/plasma-org.kde.plasma.desktop-appletsrc</code> and manually change the paths.

			=== No available locale settings in the Plasma system settings ===
			The "Region & Language" page in the Plasma system settings is somewhat broken on NixOS. Instead, edit the <code>$XDG_CONFIG_HOME/plasma-localerc</code> file.
