[PyQt] PyQt 5.7.1 SystemError: bad argument to internal function

[Shawn Douglas]

Hi,

Several of the scripts in
PyQt5_gpl-5.7.1.dev1611141011/examples/qml/referenceexamples
are failing with a SystemError exception. For example, for attached.py:

"Jack Smith" is having a birthday!
He is inviting:
Traceback (most recent call last):
  File "attached.py", line 210, in <module>
    for guest in party.guests:
SystemError: Objects/typeobject.c:2832: bad argument to internal function


Thanks,
Shawn
