The same also happens with old-style classes:

class a:

The commit 0f858f99 fixes this part of the problem. Instances of old-style classes can be easily identified by checking for PyInstance_Type. Then its type object (PyClass_Type) can be used to get all its attributes.

However, I didn't find a way to identify instances or the types of new-style classes.

Then, a "module" is also a new style class and to get all its attributes I must query the instance of the module and not its type object.

Any idea how to solve this?

I found a solution. To test for new-style classes the tp_flags is set to Py_TPFLAGS_HEAPTYPE and additionally I check that it's an instance of 'PyBaseObject_Type' (which corresponds to 'object' in Python).

And the hasattr/getattr access has been replaced with a call of Py_CompileString & PyEval_EvalCode because otherwise a property is triggered twice.

But note, when you enter 'Gui.object.test1.' into the console then test1 will be executed. I have tested this with the IDLE editor and this shows the same behaviour.
