Occasionally (like 1 in 10 times), plasmashell boots with all empty icons. And the log says it "Could not open sycoca database": 1月 20 18:19:28 laptop-jin-mi plasmashell[1591]: Could not find required file "mainscript" for package "/usr/share/plasma/plasmoids/org.kde.plasma.icontasks/"> 1月 20 18:19:29 laptop-jin-mi plasmashell[1591]: Member availWidth of the object AppletContainer_QMLTYPE_171_QML_175 overrides a member of the base object.
