  Sounds like
  
  BUG: 404518
  BUG: 411795
  
  Which we have quite a lot of dupes of :/
  
  We know this bug went away with Qt5.14, so maybe it's worth just merging this 
simple fix. 
  Wait for @notmart, but I say lets merge this into Plasma 5.17.x

  I do have a theory of what's wrong underneath.
  
  ConfigModule owns the QML context. It sets itself as a context property. 
Context properties have to outlive the QML context they are assigned.
  
  ConfigModuleDervied::~ConfigModuledDerived gets run before 
ConfigModule::~ConfigModule() which is where we delete the QML context - which 
means we have a small period of time where a QML accessing a the "kcm" config 
property is in an awkward state. I suspect something about the translations KCM 
shutdown must be triggering a binding re-evaluation at this phase.
