Hi

I'm the maintainer of the Flent tool, which uses PyQt for its GUI. I
recently got a bug report which showed odd behaviour on OS X.
Specifically, setupUi() returns:

SystemError: <built-in function connectSlotsByName> returned a result with an error set

With what appears to be an underlying: AttributeError: __getattribute__

The error seems to occur only on OS X with PyQt5. It does not occur with
PySide2. It also seems to be a new bug (the GUI has worked fine on OS X
before).

Is this a bug in PyQt, or is there something else going on here?

The bug report with more detail is here: https://github.com/tohojo/flent/issues/167

Thanks,
