> Christian, you said in an e-mail that you have a workaround -- unsetting the Py_TPFLAGS_METHOD_DESCRIPTOR. Could you point me to the commit with that workaround, so I could try exploring the code in context?

Yes, it went into gerrit here:

https://codereview.qt-project.org/c/pyside/pyside-setup/+/282705

The problem is that during PySide type creation the PyType_Ready
function looks into the mro() method, which uses this new
flag. When I temporary remove that, everything works.
