Sadly, after further test I discover that the crashes remain, so I think it is a qgis bug and not a problem in my code. The problem happens when I put my custom form into a subform widget (QgsRelationEditorWidget). If I add a new record in the subform and I move to another record using the left column QGIS crashes. It seems to be a more general problem because the crash appears also when I add some simple control that modify the object in the form.
I can open a ticket and add some test data. If it is a minor bug and it could be resolved easily I really offer a pizza and a beer to resolve it.
