Hello Christian, I would just break on that error (using chrome or safari which works good for me) and check the classname of the object not having that property. I guess it comes from a loaded model object so the class name could tell you some more details about whats actually in the class itself.
About the stacktrace itself. Thats not only a problem of the property system, it also has a lot of calls in the event system which is quite huge as well. The only advice i can give you here it to trust that qooxdoo works and ignore these calls.
