Description
Currently, it is possible to include the model itself into the model workflow thus creating a model which calls itself. Of course this causes errors.

mmm, actually it shouldn't cause error. The modeler is designed to allow nested models. So it's a bug, but the solution is not removing models in the list of algorithms in the model, but fixing it.

Sorry for being unclear :-)
It's great that modeler allows nested models! I just wanted to suggest that it might make sense to check if the user is creating circular references in his models. If model A calls model A to get to its results, it won't ever stop, or is there a way to break out of such loops?
