安装 Tor 浏览器时，可以在 ~/.local/share/applications/ 中创建一个 .desktop 条目，以便能够使用应用程序的启动器打开 tor。这对我来说是个问题。这是 .desktop 条目中的重要参数：
Exec=sh -c '"/opt/tor-browser_en-US/Browser/start-tor-browser" --detach || ([ ! -x "/opt/tor-browser_en-US/Browser/start-tor-browser" ] && "$(dirname "$*")"/Browser/start-tor-browser --detach)' dummy %k
现在执行时desktop-file-validate start-tor-browser.desktop，我收到以下错误：
start-tor-browser.desktop: hint: value item "Security" in key "Categories" in group "Desktop Entry" can be extended with another category among the following categories: Settings, or System

即使使用“\””转义“”字符后，它仍变成：
Exec=sh -c '\\"/opt/tor-browser_en-US/Browser/start-tor-browser\\" --detach || ([ ! -x \\"/opt/tor-browser_en-US/Browser/start-tor-browser\\" ] && \\"$(dirname \\"$*\\")\\"/Browser/start-tor-browser --detach)' dummy %k
我仍然收到错误：
