Example of crash, cased by it:
In AIS_ViewCube implementation (0028954) there is AIS_ViewCubeFlat not displayed in context, but there is an owner connected to it and listening selection.
The place, where the crash happens if we call it for this owner:
void AIS_InteractiveContext::AddOrRemoveSelected (const Handle(SelectMgr_EntityOwner)& theOwner, ...
const Handle(AIS_InteractiveObject) anObj = Handle(AIS_InteractiveObject)::DownCast (theOwner->Selectable());
Handle(AIS_GlobalStatus)& aStatus = myObjects.ChangeFind (anObj);
