start_kdeinit reads its environment over a pipe from start_kdeinit_wrapper. For security, each environment entry must be smaller than 4kb by default. Qt-based applications in Nixpkgs may have larger environments, and the recent upgrade to Plasma 5.17 pushed start_kdeinit_wrapper over the limit. The limit is now extended to 16kb. This problem was not detected during testing because the failure is silent: start_kdeinit will continue with an empty environment. In other circumstances, this strategy might work, but it does not work on NixOS. This failure is now treated as a fatal error. Fixes: #79707
