Delete a scene and a Urho3D class at runtime

Hi,
I wrote an application using Urho3D in QML (see https://github.com/SteveTJS/urho3DInQML) and I have a crash when deleting the Urho3D class named “Urho3DApplication” in the code.
In fact, I need to delete and create again this class at runtime.

The error I get is :

in Urho3D/Container/RefCounted.cpp line 42 : Assertion refCount_->refs_ == 0.

So I assume it is due to non deleted objects. In the Urho3DApplication destructor, I tested with :

Urho3DApplication::~Urho3DApplication()
{
    mScene->RemoveAllChildren();
    mScene->RemoveAllComponents();
    mScene->Clear();
}

and others things, but I still get the crash and the same error.
Any ideas?

You are not allowed to delete SharedPtr. Use any other technique to reset the content (Reset or assign empty).
Moreover, I suggest you to forget about C++ statement delete at all. It gives nothing but pain.

Indeed, my bad, still used to new / delete pointers.
Thanks!
