KDDockWidgets warning during startup

[GitMensch]

When starting hotspot (current AppImage) I get

kf.coreaddons: "Could not find plugin kgraphviewerpart"
void KDDockWidgets::Config::setFlags(KDDockWidgets::Config::Flags) Only use this function at startup before creating any DockWidget or MainWindow ; These are already created:  ("results") ("summary", "bottomUp", "topDown", "flameGraph", "callerCallee", "disassembly", "frequency", "timeLine") QVector()

I can't remember to have seen the second message before, so creating this issue...
