LibreOffice-Writer图标无法从KDE程序启动器的最爱(Favorites)列表中移除。

Question

LibreOffice-Writer图标无法从KDE程序启动器的最爱(Favorites)列表中移除。

我尝试过用grep工具在根目录下搜索过包含字符串‘libreoffice-writer’的文件，最后定位到了一个最符合的配置文件，即位于/etc/skel/.config的kactivitymanagerd-statsrc文件。

截取片段如下

kactivitymanagerd-statsrc：

ordering=applications:systemsettings.desktop,applications:org.kde.dolphin.desktop,applications:org.kde.kate.desktop,applications:gimp.desktop,applications:netease-cloud-music.desktop,applications:octopi.desktop,applications:org.gnome.meld.desktop,applications:org.kde.filelight.desktop,applications:org.kde.kdiff3.desktop,applications:org.kde.kfind.desktop,applications:org.xfce.Catfish.desktop,applications:realvnc-vncserver-service.desktop,applications:realvnc-vncviewer.desktop,applications:steam.desktop,applications:libreoffice-writer.desktop

我将文件中所有的包含libreoffice的字符串删除后,问题仍然存在，重启系统后Libreoffice-Writer又出现在了Favorites列表中，请问这种问题要怎么解决呢？

希望有朋友能给出有意义的回答，出于好奇提出该问题，希望大家尽量不要给出与问题无关的建议。
